Using the latest MingW32 available (gcc 3.2, for windows) I compiled tscp 1.73. A long time ago I had compiled 1.73 using intel c 5 with all optimizations and profiling and made the fastest executable for amd processors there was (you can even check the tscp benchmark site http://home.attbi.com/~tckerrigan/bench.html). Here's the results: Compiler MIPS Intel C[1] 1452.4 GCC[2] 1598.1 1 - (Profile directed) icl *.c -O2 -Qipo -QxiM -G6 -Qunroll -Qprof_use -Qprof_dir c:\profiles 2 - -O3 -march=athlon-mp -mcpu=athlon-mp -mfpmath=sse -mmmx -fomit-frame-pointer -funroll-loops -finline-functions -fprefetch-loop-arrays Those same options get 215knps with tscp 1.8. Intel gets 193knps... I'm on a dual athlon mp 1.2 ghz on a tyan tiger s2460 with 512 mb memory.
