If IO bound see about getting more IO, specifically a fast RAID controller with Battery Backed Cache, and a fair number of fast hard drives in a RAID-10. Trying to throttle one thing to get the others to run faster can only buy you so much time. As load increases you'll need more CPU or IO. If the thing you're doing is CPU intensive, and it needs lots of CPUs, then look at some form of replication to other boxes to throw more CPUs at the problem. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
