I feel that FreeBSD JDK is pretty slower than Linux JDK.

With Linpack benchmark for Java (*),
Linux JDK117 on PentiumPro/200MHz results 1.357 Mflops/s,
FreeBSD JDK117 on PentiumII/233MHz results 0.734 Mflops/s.
Java interpreter shows these results, no JIT.

(*) Linpack Benchmark -- Java Version

I wonder why isn't FreeBSD port based on Linux port.
I love FreeBSD as same as Linux, but I'm sad to say
porting effort to Linux is superior to the FreeBSD one.
