Perhaps you can use VMWare or Parallels? i.e. run Windows under OS X.

I don't have time to investigate your patch/code, but the JVMs are  
different. There may be some JVM settings which are by default used  
on windows, but not OS X, or vice versa.

One other thing. Make sure you are not stalling in the main thread  
while you don't need to be. One example is to copy your matrix to  
send, add it to a queue which is serviced by your networking thread  
(I assume you're using a separate thread for networking, which is  
*essential*).
