Hi Everyone,
I've put together a short article and posted it online regarding
performance tuning PostgreSQL in general. I believe it helps to bring
together the info in a easy to digest manner. I would appreciate any
feedback, comments, and especially any technical corrections.
The article can be found here:
http://www.revsys.com/writings/postgresql-performance.html
Thanks!

Looks nice. You should mark the link to the perf tips at Varlena.com as
"PostgreSQL 7.4" and augment it with the current version here:
www.powerpostgresql.com/PerfList
as well as the Annotated .Conf File:
www.powerpostgresql.com/Docs
For my part, I've generally seen that SATA disks still suck for read-write
applications. I generally rate 1 UltraSCSI = 2 SATA disks for anything but
a 99% read application.

I'll work this bit of wisdom in later tonight. Thanks again for the

Frank,
A couple of things I wish I had been told when I started asking how to
configure a new machine.
Use RAID 10 (striping across mirrored disks)
or RAID 0+1 (mirror a striped array) for your data.
Use RAID 1 (mirror) for your OS
Use RAID 1 (mirror) for the WAL.
Don't put anything else on the array holding the WAL.
There have been problems with Xeon processors.

Keith

Not really as I do not understand the issue.
Here is one post from the archives.
http://archives.postgresql.org/pgsql-performance/2005-05/msg00441.php
If you search the archives for xeon sooner or later you will bump into
something relevant.

My understanding is that it isn't particularly XEON processors that
is the problem
Any dual processor will exhibit the problem, XEON's with
hyperthreading exacerbate the problem though
and the good news is that it has been fixed in 8.1

Where's that ? The only information I have is a message from Tom Lane saying the
buffer manager (or something like that) locking has been redone for 8.0. Any
pointers ?

The buffer manager was the place that seemed to be hit hardest by Xeon's
problems with spinlock contention. I think we've partially fixed that
issue in 8.1, but as we continue to improve the system's performance,
it's likely to surface as a bottleneck again in other places.

I believe all of these issues are covered in the article, but
obviously not clearly enough. I'll work on rewording that section.

yikes! never tell an unsuspecting person to use mirred stripes--that
configuration has lower reliability and performance than striped mirrors
with no redeeming qualities.

Nice work! Some minor issues I saw:
* section "Understanding the process", para 5:
"Now that PostgreSQL has a plan of what it believes to be the best way
to retrieve the hardware it is time to actually get it."
Do you mean "retrieve the data" instead of "retrieve the hardware"?
* Perhaps some examples under "Disk Configuration"?
* section "Database Design and Layout", after new table layout:
"Take for example the employee table above. Your probably only display
active employees throughout the majority of the application..."
Do you mean "You're probably only displaying"?
HTH,

I did not read through the whole article, but I already have some comments;
work_mem was formerly sort_mem. As many of us still use pg7, you should
probably have a note about it.
There are already quite some short articles at the web about this issue, and
that was actually my starting point when I was assigned the task of tweaking
the database performance. I think diversity is a good thing, some of the
short articles was relatively outdated, others were not very well written.
And also - I still never had the chance to do proper benchmarking of the
impact of my changes in the configuration file, I just chose to trust some
of the advices when I saw almost the same advice repeated in several
articles.
I think we need some comprehensive chapter about this in the manual, with
plenty of pointers - or eventually some separate well-organized pages
telling about all known issues. It seems to me that many of the standard
tips here are repeating themselves over and over again.

Hi,
The article seems to dismiss RAID5 a little too quickly. For many
application types, using fast striped mirrors for the index space and
RAID5 for the data can offer quite good performance (provided a
sufficient number of spindles for the RAID5 - 5 or 6 disks or more). In
fact, random read (ie most webapps) performance of RAID5 isn't
necessarily worse than that of RAID10, and can in fact be better in some
circumstances. And, using the cheaper RAID5 might allow you to do that
separation between index and data in the first place.
Just thought I'd mention it,
Dmitri
