Well some other squeaker will need to come to the rescue.
In check on my 2.33 Ghz intel core 2 duo
I download the 3.9.x windows squeak zip file
with the included image/change files using a mac carbon vm 3.8.12b1U I  
see

However if I run that under Parallels (current version) using a dusty  
copy of windows 2000 and the 3.9.x VM in the downloaded zip
I get the data below but it's wrong since I noticed on my mac the doit  
takes under a minute to run, but the doit on windows takes
*many* minutes to run, which points to some issue with timing/clock  
interaction which like affects the numbers below.

Likely you need some who has bootcamp that can boot mac or xp/vista  
and see what the numbers are.
