'09 mac pro speed dif in 64bit kernel?

[whyrichard]

Hello,

I was wondering if '09 mac pro users noticed any speed increase when booting in the 64bit kernel... or do most not bother?

i have an '09 quad with 8 gigs ram, ssd startup drive, etc etc...

thanks,

r.

A Mac Pro might see a SMALL speed boost when using 64-bit kernel and extensions. Nothing big though.

I boot into 64 bit kernel on my 08 Mac Pro and notice a difference.
this site gives a nice breakdown of 32 bit vs 64 bit kernel performance: http://macperformanceguide.com/SnowLeopard-Performance.html
