             Summary: Are there any ways to improve performance?
                 Key: SSHD-742
                 URL: https://issues.apache.org/jira/browse/SSHD-742
             Project: MINA SSHD
          Issue Type: Question
    Affects Versions: 1.4.0
         Environment: https://github.com/maseev/sshd-echo
            Reporter: Miron Aseev
            Priority: Minor


I created a simple client-server application (see the environment section) that uses MINA SSHD library, just to test the performance. I was quite disappointed because the throughput was particularly low - 2400 requests per second on average on localhost.

According to Java Flight Recorder, the application spends most of its time in ChannelPipedInputStream/ChannelPipedOutputStream on different monitor objects.

Is there any way I can improve the performance? The documentation is kinda sparse and doesn't mention any tuning suggestions. Maybe I can avoid using these piped streams somehow or set some parameters related to the transport layer?

All suggestions are greatly appreciated.
