Ok, fyi on a 2.33 Ghz intel core 2 duo machine a *correctly tuned* VM gives
582,148,948 bytescodes/sec; 14,497,194 sends/sec
How do you tune your VM ? I've tried the Smalltalk version of Gnuification, but results are worse. So far the best I have is: -O2 -fomit-frame-pointer -mfpmath=sse -march=native -s -mtune=generic ========================================== 345479082 bytecodes/sec; 9815639 sends/sec 348536419 bytecodes/sec; 9970081 sends/sec 348299319 bytecodes/sec; 9978804 sends/sec 345013477 bytecodes/sec; 9690546 sends/sec 348299319 bytecodes/sec; 9970081 sends/sec Laurent Laffont

So what Ghz is this machine?
model name : Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz cpu MHz : 1994.987 cache size : 4096 KB

Thank you !
Here the result:
Squeak VM 3.11.3 -r 2135 + FT2Plugin + --CFLAGS="-O3 -fomit-frame-pointer -mfpmath=sse -march=native -s -mtune=generic" ========================================== 339072847 bytecodes/sec; 9560580 sends/sec 338848444 bytecodes/sec; 9552573 sends/sec 338177014 bytecodes/sec; 9473233 sends/sec 337953795 bytecodes/sec; 9496896 sends/sec 338848444 bytecodes/sec; 9496896 sends/sec
so the best performance I have so far.
