Thanks to all of you. I have changed the settings and reloaded the config. Let me run this system overnight. I will update this forum if new settings works for me. I am also asking management to upgrade the hardware. Thanks a lot.

Oh, and I'd look at your I/O subsystem. You might want to look at putting $300 hardware RAID cards with battery backed cache and 4 or so disks in a RAID10 in them. It sounds to me like you could use more I/O for your vacuuming. Vacuuming isn't CPU intensive, but it can be I/O intensive. ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
