Trustin Lee commented on DIRMINA-546:
-------------------------------------

I also did comparison against simple blocking I/O server, and I observed the following:

* MINA server has more variance in performance; this should be fine in the long term.
* In general, MINA server performs as fast as the simple blocking I/O server in terms of throughput of accepting connections.

> Reduce unnecessary system calls when a new session is created.

> So far, MINA has been setting all socket parameters for every newly created socket.  It means MINA performs several unnecessary system calls.  For exaimple, Socket.setReceiveBufferSize() is always called even if a user didn't change the default value.
