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

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.
