Squeak on Athlon 64?

Gerry Bell sent me those numbers from the 'other' 64 bit platform:

"This machine was a single processor 1.8Ghz G5.

Stock VM:

'129,620,253 bytecodes/sec; 5,241,007 sends/sec'
'125736738 bytecodes/sec; 5237113 sends/sec'
'130346232 bytecodes/sec; 5206170 sends/sec'
'130147432 bytecodes/sec; 5187016 sends/sec'
  '130147432 bytecodes/sec; 5031516 sends/sec'"

John's 500Mhz G3 powerbooks gives numbers like so

'5,1405,622 bytecodes/sec; 1,860,771 sends/sec'
'51282051 bytecodes/sec; 1873720 sends/sec'
'50673000 bytecodes/sec; 1863347 sends/sec'
'51488334 bytecodes/sec; 1839164 sends/sec'
'50996015 bytecodes/sec; 1876332 sends/sec'

Although the G5 numbers bytescodes/sec / Mhz doesn't scale right, so  
I'm wondering about
the G5 number.  For the G3 it's 0.1028112 bytecodes per Hz, but G5 says  
0.07201125 bytecodes per Hz.
I'd expect the G5 to do oh 185,000,000 bytecodes/sec


  I'll point out Gerry also submitted some macrobenchmark numbers
Total time = 246297 milliseconds.  (stock VM)
Total time = 201351 milliseconds.  (G5 specific compiled VM)

The 45 second difference has me confused. I've heard if the energy  
saver  settting isn't cranked right off
in the G5 then it will trade CPU/Heat performance for quiet (less fan  
noise).Sooo can't say
what else the G5 was doing or how fast it really was running.

PS Thanks to Gerry for collecting some numbers.
