We have multiple machines in Windows XP that has intel P4 2.8G Hz+ CPU with Hyper Threading enabled. We found Java 3D picking action become very slow, even slower than machines with less than 1G Hz CPU. The pickCanvas.pickAllSorted() method is taking more than 10 times its original time.
This has the appearances of a driver or O/S problem to me. I run a dual-CPU development machine and don't see any slowdown in picking code. Since hyperthreading is, theoretically, supposed to present 2 logical CPUs to application code, it should seem somewhat the same as a real dual CPU machine.
