> Should be most recent timing for each major subsystem for each type of call.  E.g.,
> PUT: 10ms (locking), 10ms (datacontainer), 20ms (RPC), 30ms (CacheStore).
> GET: 0ms (locking), 5ms (datacontainer), 0ms (RPC), 10ms (CacheStore).
> etc.
> Could be implemented as a simple ringbuffer, in a specific component (TimeBudgetMonitor?) just storing the most recent N calls and that's it.  Cheap to capture, cheap to store.
> This data could then be made available via a JMX operation on TimeBudgetMonitor.  This is extremely valuable for tuning and debugging perf issues.
