You're the first person I've seen to suggest that many buffers. I've read
that too many can slow down performance. I have 1.5 gigs of RAM on my
server but I'm also running a few other java programs that take up probably
500 megs total of memory, leaving me 1gig for Postgres. Should I set my
shared buffers to be 25% of 1gig? That would be 32768. Then what should my
effective cache be? Right now I have it set to 64000 which would be
512megs. Between the buffers and cache that'd be a total of 768megs,
leaving approximately 768 for my other java apps & the OS.
Sounds reasonable to me.
