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? ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
