stack commented on HBASE-6338:
------------------------------

Might not be enough of a perf gain to gamble putting it into 0.94?

> Every call in rpc handler a Method will be created, if we cache the method will improve
a little.
> I test with 0.90, Average Class.getMethod(String name, Class... parameterTypes) cost
4780 ns , if we cache it cost 2620 ns.
