I suggest you read the docs on how shared buffers work, because, reasonably, it would be all the way around. Recent improvments into how postgres manage its shared buffer pool makes them better than the OS cache, so there should be more incentive to increase them, rather than decrease them. Workload conditions may make those improvements worthless, hinting that you should decrease them. But you have to know your workload and you have to know how the shared buffers work. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
