Hi Gene,
at my postgresql.conf, the only non-comented lines are:
fsync = off
This can, and will result in lost data.
lc_messages = 'C'
lc_monetary = 'C'
lc_numeric = 'C'
lc_time = 'C'
How much memory does this machine have and what version of postgresql
are you using?
max_connections = 100
shared_buffers = 5000
temp_buffers = 1000
work_mem = 4096
The only two values I changed are shared_buffers and work_mem.

I'm using Gentoo Linux, so all my libraries (including glibc that is
very important to PostgreSQL), and all my softwares are compiled with
good CFLAG options to my processor ("-O2 march=athlon-xp (...)"). My
Linux is not an Intel-AMD binary compatible turtle like
Fedora/RedHat/SUSE/... It's really important to have your GLIBC
compiled for your processor. It is essencial for performance.
I can't imagine anyone buying a $1k-dollar quad-core XEON and using an
i585 compatible distro that doesn't even know what the fudge is
SSE/SSE2/vectorized instructions.
Best regards,

I have a similar type application, I'm partitioning using constraint
exclusion so queries only have to look at a few tables. I've found
that
there is some overhead to using partitioning so you should test to
see how
many partitions you want to create. Could I check out you
postgresql.conf
parameters to compare? thanks
