The daemon in larger-scale testing can prevent potential skews in the test results by keeping the JVM warm.
The daemon is only available in tarball installations. Run the daemon from:
install_location/tools/bin/cassandra-stressd start|stop|status [-h <host>]
During stress testing, you can keep the daemon running and send it commands through it using the --send-to option.
