Thanks a lot for the help Graham and Robert! Will try increasing heap and see how it goes.
Here are my gc settings, if they're still helpful (they're mostly the defaults): -Xms6G -Xmx6G -Xmn400M -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:SurvivorRatio=8 -XX:MaxTenuringThreshold=1 -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+UseTLAB -XX:+CMSParallelInitialMarkEnabled -XX:+CMSEdenChunksRecordAlways On Wed, Dec 3, 2014 at 2:17 AM, Jason Wee <peich...@gmail.com> wrote: > ack and many thanks for the tips and help.. > > jason > > On Wed, Dec 3, 2014 at 4:49 AM, Robert Coli <rc...@eventbrite.com> wrote: > >> On Mon, Dec 1, 2014 at 11:07 PM, Jason Wee <peich...@gmail.com> wrote: >> >>> Hi Rob, any recommended documentation on describing >>> explanation/configuration of the JVM heap and permanent generation ?
