FreeBSD > 4.4-RELEASE on EV56. The last I tried, the Tru64 JDK was blindingly fast, and the Linux JDK was turtle slow. However, this is a moot point since the Tru64 JDK will not run on FreeBSD. It uses the Tru64 threads library. This threads lib makes Mach system calls which we do not emulate. FWIW, the Linux JDK was just as slow running natively. I haven't played with java in any meaningful way since 1.2.x, so they may have improved the speed of the Linux JDK since then.
