Compared to e.g. an OpenSSH server you will lack certain functionalities like privilege separation or integration with the OS user management (PAM or whatever on Linux). For general shell-level access...

Look in [the documentation](https://github.com/apache/mina-sshd/blob/master/docs/server-setup.md) or in the tests.

Use the latest.

Why should a newer library be much faster? It's the same protocol. If both are programmed correctly, they should have about the same performance. My local tests show that with...

Also see #485. The transfer speed may also depend on how exactly your code transfers files.

Closing this. If AES encryption was used, the slowness can be explained and should be fixed with the fixes made for issue #524.

Thank you for this test case. It appears that there is indeed something wrong with the `FileChannel`s. The following is in my tests much faster (and on par with OpenSSH...

Interesting: if you change in your code ``` readableChannel.transferTo(0, length, writeableChannel); ``` to ``` writeableChannel.transferFrom(readableChannel, 0, length); ``` it will also run much faster (but still 25% slower than the...
