So i try a simple 50000 loop with a calcul in it. i've done a time mesure and the code generated is really NOT speed comparing to what the watcom c gives to me. it run 2 times better in watcom flat mode. i've used -o2 -forcemem -forceaddr -fstrengh... flags. (and perhaps some other one). could someone help me ? kst AT imaginet DOT fr
