Hi,
I have just upgraded our db from 7.4.2 to 8.0.1 and we are doing some testing. For some reason, we have discovered that our application performs much slower on 8.0.1.
My initial reaction was to turn on log_min_duration_statement to see what's happening. However, log_min_duration_statement does not work for JDBC clients in 8.0.1.
As a result, I modified log_statement to all. Without my application doing anything, I see statements below being executed non-stop. Who is triggering these statemetns? Is this normal? What am I doing wrong?
I am using Fedora Core 1 - Kernel: 2.4.22-1.2174.nptl
Please help. Thanks.
