Thank you for help :) I'm giving 2048M the JVM for each node. CPU load is jumping 70-90%. Memory usage is increasing to max during testing (probably cache is filling). I/O I didn't monitor.
I'd like to see answers on my other questions. 2012/6/13 Erick Erickson <erickerick...@gmail.com> > How much memory are you giving the JVM?
