Re: Autovacuum is running forever

We are having only two disk (40GB each). One disk is used for OS, App
Server, and application. Second disk is used for postgresql database.
It's a dual cpu machine having 2 GB of ram.

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.
