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).
