In normal conditions the postgres process uses about 3% of cpu time but when is in "degraded" conditions it can use up to 25% of cpu time. The load of my server is composed of many INSERTs on a table, and many UPDATEs and SELECT on another table, no DELETEs. I tried to run vacuum by the pg_maintenance script (Debian Lenny) but it doesn't help. (I have autovacuum off). So, my main question is.. how can just a plain simple restart of postgres restore the original performance (3% cpu time)? I can post my postgresql.conf if needed.
