Does the program use disk I/O significant proportion of its run time? 
Does it swap to disk?  If so, your disk cache can skew the run time a
great deal. 

Another possibility might be the size of your innermost loop: if it 
sometimes overflows the CPU caches, you will see a factor of 2-4 in 
performance without any apparent explanation.

Huh?  Is this program compiled with DJGPP v1.12?  If it's v2.01, run 
go32-v2, not go32 (it's a completely different program, and reports 
completely different results).
