CpuRatioTimer	CpuRatioTimer is a composite Timer that is backed by two other Timer objects -- e.g.
CpuSpeedExtractorFactory	Creates a CpuSpeedExtractor that can be used to determine the speed of the CPUs on the current machine.
JmxGcTimerSet	JmxGcTimerSet creates timers that measures the amount of time spent in garbage collection while the timer was running.
JmxHotspotTimerSet	JmxHotspotTimerSet creates timers that measures the amount of time spent in Hotspot compilation while each timer was running.
TimerFactory	TimerFactory creates new Timer instances.
