There must be something wrong. My T8300 notebook had about 550M
bytecodes/sec and 15M sends/sec on linux. With the stock windows vm I have
500M bytecodes/sec and 14.5M sends/sec.


With the source I have provided ? 32bits ?

My linux vm was 32-bit with some older sources. Since I don't have linux on my notebook anymore I can't tell which version it was.




�On MacOSX, same laptop, with Squeak VM 4.2.2 beta 1U from pharo website

449122807 bytecodes/sec; 9649554 sends/sec
405384006 bytecodes/sec; 9584683 sends/sec
445604873 bytecodes/sec; 10138464 sends/sec
445993031 bytecodes/sec; 10102544 sends/sec
446381865 bytecodes/sec; 10174641 sends/sec

compared to Linux


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 it seems there's� improvements that can be done on Linux VM, but there's not so much difference.


I think everybody know this and that your results is the expected. I even remember some threads were we discussed the same. For example, I found this one:

http://n4.nabble.com/Pharo-apparently-slow-on-linux-td1304643.html#a1304643

but there are more.
The MacOS VM is faster than the rest, even with the same PC.
I have no idea how to improve Linux's one, thus.

Cheers

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

337953795 bytecodes/sec; 9496896 sends/sec
338848444 bytecodes/sec; 9496896 sends/sec

so the best performance I have so far.
