Thanks, Josh. The only reason I tried 8.4 first is that it was available for Debian as compiled package, so it was simpler for me to do it. Anyway I am going to test 9.1 too. I will post about the results.

It is fairly likely that the difference you're seeing here is due to improvements made in checkpointing and other operations made between 8.4 and 9.1.
Is there some reason you didn't test 9.1 on Linux to compare the two? -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com
