I have yet to change my Java arguments yet for this multi-core change not sure if its effecting any of the current Java Arguments I've had in the past. Here's what I'm running... -d64 -XX:+UseCompressedOops -server -XX:NewSize=84m -XX:+UseAdaptiveGCBoundary -XX:NewRatio=3 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:MaxGCPauseMillis=10 -XX:GCPauseIntervalMillis=50 -XX:MaxGCMinorPauseMillis=7 -XX:+ExplicitGCInvokesConcurrent -XX:+BindGCTaskThreadsToCPUs What about everyone else?
