    What's the -XX:ParallelGCThreads option setting dependent on ?

      physical processors or logical processors , and the logical processors are total cores of physical processors * per cores of a physical processor.

      The number of garbage collection threads. The default would be equal to the processor count, which would probably be unnecessarily high on a 32 thread capable system.

      in ibm.com site, an article said it should be logical processors(cores), can we find the explanation from sun hotspot jvm source code ?

      Thanks !
