+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

+GiST and Encryption
+-------------------
+
+GiST uses LSNs and NSNs for concurrency. This means that unlogged and
+temporary relations also need LSNs. GiST has a mechanism to assign LSNs
+to such relations, but sometimes uses fixed LSNs and or calls
+gistGetFakeLSN(), which can cause duplicate LSNs to be used. Therefore,
+when encryption is enabled and fake LSNs are needed, the GiST code calls
+LSNForEncryption(). See src/backend/crypto/README for more details.

Could you get a profile with call graphs? We need to know what leads to all
those osq_lock calls.
perf record --call-graph dwarf -a sleep 1
or such should do the trick, if run while the workload is running.

I think it's unwise to compare builds of such different vintage. The compiler
options and compiler version can have substantial effects.

I recommend also using -P1. Particularly when using unix sockets, the
specifics of how client threads and server threads are scheduled plays a huge
role. How large a role can change significantly between runs and between
fairly minor changes to how things are executed (e.g. between major PG
versions).
E.g. on my workstation (two sockets, 10 cores/20 threads each), with 32
clients, performance changes back and forth between ~600k and ~850k. Whereas
with 42 clients, it's steadily at 1.1M, with little variance.
I also have seen very odd behaviour on larger machines when
/proc/sys/kernel/sched_autogroup_enabled is set to 1.

I've seen such issues in the past, primarily due to contention internal to
cgroups, when the memory controller is enabled. IIRC that could be alleviated
to a substantial degree with cgroup.memory=nokmem.

FWIW, this is with linux 6.2.12, compiled by myself though.

Fair suggestions, those graphs come out of pgbench-tools where I profile
all the latency, fast results for me are ruler flat. It's taken me several
generations of water cooling experiments to reach that point, but even that
only buys me 10 seconds before I can overload a CPU to higher latency with
tougher workloads. Here's a few seconds of slightly updated examples, now
with matching PGDG sourced 14+15 on the 5950X and with
sched_autogroup_enabled=0 too:

I cannot express on-list how much I dislike everything about the cgroups
code. Let me dig up the right call graph data first and will know more
then. The thing that keeps me from chasing kernel tuning too hard is
seeing the PG14 go perfectly every time. This is a really weird one. All
the suggestions much appreciated.

You might need to add --no-children to the perf report invocation, otherwise
it'll show you the call graph inverted.

Let me start with the happy ending to this thread:
$ pgbench -S -T 10 -c 32 -j 32 -M prepared -P 1 pgbench
pgbench (15.3 (Ubuntu 15.3-1.pgdg23.04+1))

tps = 1077739.910163 (without initial connection time)
Which even seems a whole 0.9% faster than 14 on this hardware! The wonders
never cease.

My problem was not writing kernel symbols out, I was only getting addresses
for some reason. This worked:
sudo perf record -g --call-graph dwarf -d --phys-data -a sleep 1
perf report --stdio
And once I looked at the stack trace I immediately saw the problem, fixed
the config option, and this report is now closed as PEBKAC on my part.
Somehow I didn't notice the 15 installs on both systems had
log_min_duration_statement=0, and that's why the performance kept dropping
*only* on the fastest runs.
What I've learned today then is that if someone sees osq_lock in simple
perf top out on oddly slow server, it's possible they are overloading a
device writing out log file data, and leaving out the boring parts the call
trace you might see is:
EmitErrorReport
__GI___libc_write
ksys_write
__fdget_pos
mutex_lock
__mutex_lock_slowpath
__mutex_lock.constprop.0
71.20% osq_lock
Everyone was stuck trying to find the end of the log file to write to it,
and that was the entirety of the problem. Hope that call trace and info
helps out some future goofball making the same mistake. I'd wager this
will come up again.
Thanks to everyone who helped out and I'm looking forward to PG16 testing
now that I have this rusty, embarrassing warm-up out of the way.

There is no mention of perf or similar utilities in pgbench-tools
docs. I'm guessing Linux is the primary platform pgbench-tools gets
used on most. If so, I think it'd be useful to mention these tools and
snippets in there to make others lives easier, when they find
themselves scratching heads.

That's a good idea. I've written out guides multiple times for customers
who are crashing and need to learn about stack traces, to help them becomes
self-sufficient with the troubleshooting parts it's impractical for me to
do for them. If I can talk people through gdb, I can teach them perf. I
have a lot of time to work on pgbench-tools set aside this summer, gonna
finally deprecate the gnuplot backend and make every graph as nice as the
ones I shared here.
I haven't been aggressive about pushing perf because a lot of customers at
Crunchy--a disproportionately larger number than typical I suspect--have
operations restrictions that just don't allow DBAs direct access to a
server's command line. So perf commands are just out of reach before we
even get to the permissions it requires. I may have to do something really
wild to help them, like see if the right permissions setup would allow
PL/python3 or similar to orchestrate a perf session in a SQL function.

Do you know why using phys-data would have solved the problem in your
particular setup? I find figuring out what perf options I need
mystifying.
I end up trying random things from
https://wiki.postgresql.org/wiki/Profiling_with_perf, the perf man
page, and https://www.brendangregg.com/perf.html
The pg wiki page actually has a lot of detail. If you think your
particular problem is something others would encounter, it could be
good to add it there.
FWIW, I think it is helpful to have hackers threads like this where
people work through unexplained performance results with others in the
community.
