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.

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.
Maybe I express wrongly myself. I said several times (even in this thread) I was a newbie. I said that all the VMs I have tried for Linux are slower than the one I tried for Mac OS. At least the ones that are available for us without needing to be a VM guru. And it seems I was not the only to notice that.
