I downloaded GCC 2.8.1 and DJGPP 2.02 and I noticed a performance
decrease. If you remember thomas djafari's test, I get these numbers:

DJGPP v 2.7.2.1

 4234 millions clocks
 3170 millions clocks

my djgpp 2.7.2.1
3828 millions clocks
2749 millions clocks

PGCC 1.0.1

3132 mil clocks
2574 mil clocks

gcc 2.8.1 486
4183 millions clocks
2422 millions clocks


Did you get a performance increase when you switched to gcc 2.8.1?
Especially with Allegro, what happened?

Should I stick to PGCC?

also, I'm confused about GCC 2.8.1 and DJGPP 2.02.
what is the difference?
Can I get DJGPP 2.02 and still use GCC 2.7.2.1 or PGCC?

Finally, how can I get the max performance with DJGPP and Allegro on a
P133? (which GCC version, 2.7.2.1, 2.8.1 or PGCC 1.0.1, which BNU
version, which DJGPP version, 2.01 or 2.02 ?)
Thank you (this is important for me)
