Comment (by caeies):

 Ok reading you code, I think that the main problem is that you are waiting
 for the ACK before continuing to send data, while openSSH just send stuff
 as fast as it can until he fills the queue, then check for ACK when the
 sent queue is filled ...

 Hope this helps,


 Caeies (good night).
