With that kind of RAM and that kind of shared buffers setting, you must set
effective OS cache size so that postgresql can calculate when to flush buffers.
While tuning database, it always help to pin down the target first and then try
to reach it. If you could let us know what performance you are expecting out of
this machine and for what kind of load in terms of concurrent users, database
size and usage pattern etc., that would help.
