[jboss-user] [Performance Tuning] - Re: About the UseParallelOldGC

[cytchiu]

Thank you Peter. Can I say?

The problem typically happens when there are too many parallelOldGC
threads in the process and there is too small an old generation. This
results in excessive work stealing between the GC threads and this
work stealing bangs on a lock. Too many ParallelOldGC threads without
enough old space to carve up between them result in this work stealing
pathology.
