"neither windows or linux were optimised"
But doesn't that largely invalidate the test? It's very easy to set up
poorly-tuned versions of Windows or Linux. If you simply install both systems
out-of-the-box, you're comparing apples and oranges. This is especially true
if you're comparing Red Hat Enterprise Linux vs. Windows XP Pro, a desktop
operating system! XP Pro is most certainly not tuned out-of-the-box to be a
server platform.
If you have actual test data it would be helpful to publish it so others can
try to reproduce it. But I will continue to insist that there is FAR more
performance variation in other aspects of the system than in the simple choice
of which operating system is used.

We have been testing mapserver on both linux (rhel 3.x) and windows (xp
pro) for performance testing. I can't remember the exact results (someone else
on our team did the actual testing) but on high end hardware (Dell dual xeon
3ghz 4gb ram) ms on linux approached 50% higher load than on windows. I'll
have to check next week just how the test were done but the decision was
clearly in favour of linux. I do know that neither windows or linux were
optimised and the feeling was we could extend the linux performance
considerably (by doing things like not running X etc).
