Re: New to PostgreSQL, performance considerations

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

I used exactly the options you said you used.
