SSH Authentication is slow |

Hi I was wondering if there is a way to speed up the SSH password authentication process. Currently, it takes 3+ seconds to authenticate. If I'm connecting multiple times to just run a basic script, this is a hassle.
Based on the log file, it looks like the authentication itself is fast, but possibly starting the shell is for some reason slow?

Below is the log, Notice the 3 second delay after the authentication and before the connection being closed. All I ran was an ipconfig command that takes less than a second to run.

Ok I figured out which line of code it's slow on. For some reason, the ReadFirstPacket function takes most of the time of the 3 seconds. Is there a way to speed that up?

Narrowed it down a little more to the cryptPopData call inside the comm.Receive function. Any reason why this would be slow?
