G'day That will probably be the JVM doing garbage collection. Nothing much happens while it is being done.

The throughput is around 160 http transactions/sec. Every 50-100 seconds, jmeter is pausing for a few seconds not sending out any packets. I relate this to the CPU history below. I see that one CPU is 0% idle while other CPU is pretty free. I tried jmeter GUI and command line, same result. Your help is highly appreciated.
