My Java 1.4.2 in FreeBSD was only slightly slower than sun java 1.4.2  
on linux and slightly more slower than on Solaris 10, but not at all  
by the margins you mention.  Just a point of reference.  The java I  
was running was some compute intensive "benchmarks" and some  
production web app (WebObjects) code.

I have not yet built a 1.5 on FreeBSD.  I am on a server only, no  
display, so I have been building my own and not using the diablo  
stuff at all.
