Are there any compile options I should use when compiling(configure) posgresql-9.1.7 from source on a new centos 6.3 box? Just wondering what different gcc compile options are used in the postgresql 9.1 centos RPM that we could copy in an effort to increase kernel performance, get higher TPS on pgbench.
You can see what the current RPM build uses by executing pg_config, which will show the CFLAGS, configure options, etc.
Does pgbench even do any CPU-intensive operations? If it's disk I/O-bound, compiler optimizations aren't going to make any difference.
Cheers,
