PG is really *much* happier if you have only one backend per CPU in your
system. The way to get there is by using a connection pooler like
pg_bouncer and configuring it based on how many CPUs you have.
pg_bouncer can also provide stats for you.
Thanks,

Hum.. I had not thought of that. My current setup uses 40 max
connections, and I don't think I've ever hit it. I use apache and php,
and my db connections are not persistent.
If I did plugin pg_bouncer, is it worth switching my php from pg_connect
to pg_pconnect?
I'd bet plugging in pg_bouncer now while I'm not too busy would help me
grow in the long run, huh? I like the sound of that. Thanks!
