properties Supported properties: Note that if additional properties are to be added here, recall to also add them to the dev-build.xml file; the 'perfclient' target.

Constructor Summary

PerformanceClient()

Method Summary

static void	generateTraffic(int duration) Generate traffic at a fixed-rate for the given duration.
static java.util.TimerTask	getDelayTimerTask() Returns a TimerTask that can be scheduled at fixed-rate intervals, as required by the performance measurements.
static java.util.TimerTask	getThroughputTimerTask() Returns a TimerTask that should be scheduled only once, as the run method of the timer task will perform repeated invocations and measure the duration, and count the number of invocations to determine the throughput measure (Inovcations / Second).
static void	main(java.lang.String[] argv)
