I have developed the object which draws graphs from data enclosed in the ASCI file. The code processes multiple inputs from the mouse by reading mouse clicks and movements  The code runs fine on any Intel computer including slow laptops with as little as 1 GB of RAM. However, when I try to execute it on the computer using newest Supermicro/AMD (2 GHz Opteron) hardware, it runs very slow, eventually almost locking operating system of this double processor computer with 16 cores; computer has 16 GB of RAM. I tried practically everything from reinstalling Java to running code under different operating systems I have on this computer, including Windows XP*32, Windows XP*64, Server 2008 R2*64. The Processing code cause the same symptoms on each operating system, it looks like it just don’t run on AMD multiprocessor machine, which is really strange. I also have set the affinity of Java in the Task Manager to one core, but that also does not make any difference.

Does anyone have idea what might cause this problem?
