Description ecerichter 2013-07-23 20:40:15 UTC 
In page http://wiki.netbeans.org/FaqGCPauses
there are some explanation about using UseConcMarkSweepGC would reduce pauses during GC.
I've found that option ExplicitGCInvokesConcurrent (to be used together UseConcMarkSweepGC) would also benefit developer in multiprocessor/multicore machines.

Detailed documentation about performance tunning and specially those options can be found here:
