We may want to start looking at query plans for the slowest queries.
Use explain analyze to find them and attach them here.  I kinda have a
feeling you're running into a limit on the speed of your memory
though, and there's no real cure for that.  You can buy a little time
with some query or db tuning, but 250 or more concurrent users is a
LOT.
