--------------------------------------

I think FB guys were talking about the same thing in http://hadoopstack.com/improving-hbase-read-performance/.
+1 to the idea.

> Current RPC framework is single listener thread with multiple Reader thread, this is
pretty similar with thrift's THsHaServer design. And from thrift0.8, TThreadedSelectorServer
was introduced to meet network-io-bound scenario better. There's a benchmark report on it:

> I think we could make HBaseServer's listener multi-thread as well.  Just a raw thought
now, no patch available yet.
