FYI,
Got this article today in JDJ newsletter. May be of interest.

I did not realize that there are client and server jvm's to choose from
when java apps are launched and that the server JVM is the fastest jvm,
so I checked the OS X Server jvm.cfg file in
/System/Library/Frameworks/JavaVM.framework/Versions/1.4.2/Home/lib
to find that the server jvm (listed first in the file is the default
for java apps on OS X Server which is good, HOWEVER in the same
location on my regular OS X dev machine the default jvm is the SLOWER
client jvm.
You can easily change this on your OS X client (not Server) by
replacing jvm.cfg with a copy of server_jvm.cfg (which can be found in
the same directory). This might make a difference to the performance of
java applications such as Eclipse for those who are interested. If you
find that it does, let us know.
I hope this is of interest to the list
