Ok thanks, I'm trying to understand this to see what can be done about this to
improve libssh2 performance.
What requests do libssh2 send that it waits for a response to that the openssh
tools don't? I'm looking at the code for a simple SCP download case, and I
don't see it.
Can you be a bit more specific and mention exact protocol details or perhaps
libssh2 source code functions/snippets that is the culprit of this mentioned
restriction?
