Hi,
I'm running Postgres 7.4.6 on a dedicated server with about 1.5gigs of ram.
Running scripts locally, it takes about 1.5x longer than mysql, and the loa=
d=20
on the server is only about 21%.
I upped the sort_mem to 8192 (kB), and shared_buffers and=20
effective_cache_size to 65536 (512MB), but neither the timing nor the serve=
r=20
load have changed at all. FYI, I'm going to be working on data sets in the=
=20
order of GB.
 I think I've gone about as far as I can with google.. can anybody give me=
=20
some advice on how to improve the raw performance before I start looking at=
=20
code changes?
 Thanks in advance.
