I have been comparing Linux & Windows 2000 on the same machine:
Pentium 3 800 MHz, 384 MB RAM. Linux wins the time_test2 comparison by
about 10 % (though Windows tries to cheat on the geometric mean by
recording a zero time for one of the tests).

However, as I reported in another thread, Linux is definitely slower
overall at object graphics, and 8 times (!) slower at a
surface-animation application that is fairly typical of my usage of
IDL. The reasons for this are still being investigated...

So, before you migrate, you should check it out for yourself. (But you
knew that didn't you?)
