I'll recompile and MAL> rerun the benchmark. When I was working in the CALL_FUNCTION revision, I compared 2.0 final with my development working using -O3. At that time, I saw no significant performance difference between the two. And I did notice a difference between -O2 and -O3. The strange thing is that I notice a difference between -O2 and -O3 with 2.1a1, but in the opposite direction. On pystone, python -O2 runs consistently faster than -O3; the difference is .05 sec on my machine. Jeremy
