AFAIK the largest sensible value is 16MB - I doubt increasing it further will improve performance. Second - effective_cache_size is just a hint how much memory is used by the operating system for filesystem cache. So this does not influence amount of allocated memory in any way. > but Still Postgres Server uses Swap Memory While SELECT & INSERT into > database tables. Are you sure it's PostgreSQL. What else is running on the box? Have you analyzed why the SQL queries are slow (using EXPLAIN)? regards Tomas -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
