In addition, was on OS running a window manager and the other not? Was 
one running ssh and the other not, was FBSD running Linux emu? ... Was 
one running (insert program) and the other not...

When you run each side by side, process for process, thread for thread, 
version for version - nothing extra on one over the other, then post 
your results.

Funny thing about polls/tests/ etc. the results can be portrayed to 
reflect one biased point of view over another.

I apologize for my cynicism - but I don't put a heck of a lot of faith 
in any type of poll (in your case, a test) that can be tainted by the 
slightest bit of prejudice.
