Biggest speedup I've found yet is the backup process (PG_DUMP --> GZIP). 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.
Isn't this a major kernel bump too? So a different scheduler, different IO scheduler, etc?
I'm sure there's some speedup due to the kernel bump. I really didn't have the patience to even burn the FC2 32-bit CDs much less install both 32-bit & 64-bit FC2 in order to have a more accurate baseline comparison.
However, that being said -- when you see huge speed increases like 50% 100% for dump+gzip, it's doubtful the kernel/process scheduler/IO scheduler could have made that drastic of a difference. Maybe somebody else who has done a 2.4 -> 2.6 upgrade can give us a baseline to subtract from my numbers.
