You're probably just as well off if you let your OS deal with caching the
underlying file. What figures are you getting (use the "free" command if in
linux). It might be that you've given Postgresql *too* much memory, and
that's interfering with your OS.
Could you provide brief hardware specs, the size of the table concerned, time
taken?
