Well, I do have a SMP system and a multithreaded Java application (I
thought even the simple AWT is multithreaded, so every app using the AWT
might be too). You can increse performance by using the -native flag to
force the VM to use native threads, which then will be distributed on the
two processors. The only problem - as I experienced it - is that native
threads are not very stable so once in a while my java process crashes ...
Maybe I will try a more simple application using just two threads doing
some number-crunching .. but that will be in the near future.
