stack updated HBASE-12684:
--------------------------
Attachment: Screen Shot 2015-01-11 at 11.55.32 PM.png
Here is a rough graph of 1 and 25 threads. I did the branch-1 clean first
(first 1 thread and then 25 threads). I then stopped the cluster and did the
epoll patch running a 1 thread test followed by a 25 thread test.
While the one thread epoll has less throughput, the 25 thread test has same as
the clean branch-1.

> With the changes in HBASE-12597 it is possible to add new RpcClients. This
> issue is about adding a new Async RpcClient which would enable HBase to do
> non blocking protobuf service communication.
> Besides delivering a new AsyncRpcClient I would also like to ask the question
> what it would take to replace the current RpcClient? This would enable to
> simplify async code in some next issues.
