I think it's very likely that at least some of the Java implementations
available for Linux suck performance-wise compared to Windows. Java's
quite a poor development platform on Linux; it doesn't help that the Sun
JDK is non-free so people generally can't hack on it, and the free JVMs
have only started to receive attention relatively recently.
I'm afraid I wouldn't regard a Java benchmark as a remotely fair
assessment of any difference between Linux and XP in themselves, whether
or not millions of people use it. I also don't think that counting is a
very interesting benchmark really. :)
