Re: performance issues

Thank you Tom. That has seemed to help substantially.
I received another sugestion to increase -B 30000 which would give 240
meg. to postgres. I plan to give that a try. I've already reset the
SHMMAX val in sysctl to accomodate that size. Do you see any reason not
to try this? My thought is if some is good, more must be better. :)
Also I noticed in this artice:
http://www.ca.postgresql.org/docs/faq-english.html#3.7
mention of another memory parameter (-S), however the elephant book
refers to -S as silent mode.
Could you clarify this?
