Mike, I'm making some other tests here at another hardware (also Gentoo). I found out that PostgreSQL stops for a while if I change the -t parameter on bgbench from 600 to 1000 and I have ~150 tps instead of ~950tps. I don't know why PostgreSQL stoped, but it was longer than 5 seconds and my disk IO was comsuming 100% of my CPU time during this period. And I'm testing with my fsync turned off. Maybe if you lower your -t rate you are going to see this improvement. Best regards, Daniel On 12/12/06, Michael Stone <mstone+postgres@xxxxxxxxx> wrote:
