Hello, I compiled latest snapshot from the gcc compiler again, and measured speed difference using -O9 -fexpensive-optimizations -mcpu=pentiumpro -march=pentiumpro etcetera MSVC i compile using -O2 -G6 That creates for msvc 486 code which is scheduled for p6 though. Now at PII it used to be about 8.5% faster for msvc, but at the new PIII the speed difference has gotten a lot larger. it's 10.81% speed difference now. So that's 10.8 in short, which is 2.3% worse as it used to be. I measured on both OSes with the parallel version running single cpu. So for the single cpu version the difference will be even larger, as i lock in assembly (thanks bob!) both for linux and windows.
