I ran quite a few file system benchmarks in RHAS x86-64 and FC2 x86-64
on a Sun V40z - I did see very consistent 50% improvements in bonnie++
moving from RHAS to FC2 with ext2/ext3 on SAN.

I just finished upgrading the OS on our Opteron 148 from Redhat9 to
Fedora FC2 X86_64 with full recompiles of Postgres/Apache/Perl/Samba/etc.
The verdict: a definite performance improvement. I tested just a few CPU
intensive queries and many of them are a good 30%-50% faster.

100% faster in 64-bit mode. This drastic speed might be more the result
of 64-bit GZIP though as I've seen benchmarks in the past showing
encryption/compression running 2 or 3 times faster in 64-bit mode versus
32-bit.
I gave -O3 a try with -funroll-loops, -fomit-frame-pointer and a few
others. Seemed to perform about the same as the default -O2 so I just
left it as -O2.

Hi Willian,
Which are the GCC flags that you it used to compile PostgreSQL?
Best regards,
