Has anyone done any actual benchmark tests that show 64-bit vs 32-bit
environments/distributions with Athlon64 processors. If so, I love to see
the results. I too elected to stick with 32-bit, using the same
reasoning/guessing above.
Some months ago, on a 2GHz San Diego (4000+) I ran some tests using
linuxfromscratch with 2.6.11.11, 1 GB PC3200, ext3, 5 runs of each
(a) specific oggenc and photo manipulations in parallel
64-bit kernel, total time 246.053 to 257.601 sec, avg 250.022, std dev
4.62415
32-bit kernel, total time 247.572 to 258.963 sec, avg 252.405, std dev
4.22909
pure64, total time 172.942 to 177.532 sec, avg 174.582, std dev
1.90047
At that time, I hadn't built multilib.
