Hi:
A really simple question: I wanna set up some WAL related config
parameter. I am wondering is it the same to add those parameter on
postgresql.conf as to add them on /etc/rc.d/init.d/postgres.init??

Hi,
I am about to put a 7.1.2 server into production on RedHat 7.1
The server will be dedicated to PostgreSQL, running a bare minimum of
additional services.
If anyone has already tuned the configurable parameters on a dual PIII w/
1GB RAM then I
will have a great place to start for my performance tuning!
When I'm done I'll be posting my results here for the next first timer that
comes along.
Thanks in advance,
Adam

i am running the same hardware and postgresql 7.1.2
but i didnt tuned it because its fast enough for my purpose. But i am very
interested in your investigations. Could you please pm me, if you have
something of interest?
thanks

I have a similar system. It's a dual PII-450MHz Xeon with 512MB of RAM
running RH7.1 and 7.1.2. As far as performance tuning goes, here's the
relevant lines from the postgresql.conf file we're using:
max_connections = 64 # 1-1024
sort_mem = 8192
shared_buffers = 192
fsync = false
Obviously, depending on your needs, you can adjust those. If you've
got a 1GB of RAM, I'd set everything high and not worry about it.

Hi all,
Just added these figures to a new document :
http://techdocs.postgresql.org/techdocs/perftuningfigures.php
As people provide/submit figures and details of the equipment they use,
I'll post them onto this page.
Hopefully it will become a good set of real world guidelines for people,
etc.
Standardised benchmarks would be nice to though.
:-)
Regards and best wishes,
Justin Clift

Sure would be nice....
Here's some preliminary results of my testing...
System: RedHat Linux 7.1, kernel 2.4.3smp (i686)
Dual PIII 733 / 133FSB 1024MB RAM
2 18Gb 10000rpm U160 SCSI drives, hardware RAID1
added to /etc/sysctl.conf:
kernel.shmmax = 268435456
kernel.shmall = 268435456
PG 7.1.2
postgresql-7.1.2-4PGDG binary rpm set
relevant entries from postgresql.conf:
max_connections = 32
sort_mem = 4096
shared_buffers = 32000
fsync = true
The only benchmark I have is almost useless but I'll put it here anyway...
time ./pg_regress --schedule=parallel_schedule
(using postmaster on Unix socket, default port)
...
...
======================
All 76 tests passed.
======================
real 0m40.784s
user 0m1.980s
sys 0m1.220s

I've just did a quick read of Bruce's article in Linux Journal. My take
is this is more than a hardware issue. Table size, indexes (indices?)
verses sequential scans will come into play. I don't think you can even
really test without some relevant data, queries, etc.
Again this was a very quick read of the article.
Thanks Bruce. It looks enlightening.
Cheers,
Rod
