Linux versus Windows....

Hi,
I wrote a little generic bench marking utility for UCI engines. See
http://alpha.uhasselt.be/Research/Algeb ... nch/devel/
The idea was to be able to quickly and routinely compare different OS'es, CPU's, compilers etc (for the same engine). This came out of some discussions at the Toga development forum.
I ran some tests in Linux and Windows. You can find the results on the above URL. The tests were run on a laptop with a Pentium M@1.6GHz.
Two noteworthy conclusions.
(1) A Windows engine generally runs at the same speed under wine as on native Windows.
(2) I made a Linux binary of Toga II 1.4b5c with the Intel compiler. Strangely enough it seems to run slower than the corresponding Windows binary which is made with the same compiler. I suspect this is an issue of compiler options. I still have to investigate this (although any pointers to "magic" compiler options would be welcome).
I am kind of curious what the situation on OSX is.
Regards,
Michel
