I think we should:
1 - do updated SCP measurements on current libssh2 CVS code and compare to
recent openssh tools.
2 - work on making SCP perform roughly at the same speed as openssh - or more.
We should do profiling etc to see where time is spent and where we should
focus our efforts.
3 - measure SFTP performance (when large buffers are used by the client)
4 - adjust the SFTP API slightly and adapt code to improve SFTP performance
5 - smile
Now, all we need is lots of time...
