As it turns out, the evidence that led me to believe that FreeBSD Java
support outscaled Windows 2000's was off.
Windows 2000 comes with terrible out-of-the-box defaults, plus I
made a naive configuration change early on without understanding the
consequences.
In fact, we found that 2,000 siumultaneous Tomcat processors was
impossible to support on FreeBSD 4.8-STABLE, and unworkably slow on
FreeBSD 5.1-CURRENT (native jdk1.4.1p3 in both cases).
What I got wrong with the Windows 2000 installation:

Why I wouldn't recommend FreeBSD Java for heavily threaded applications
