Trying to determine why OpenVPN was pulling 1mbps down. The server has a dedicated 1gbps connection so I am sure the server can't be the bottleneck. I just started playing around with tls-crypt and was curious if trying to do this to make traffic look like HTTPS/TLS is the issue.
I reduced all the encryption to the minimum to see if that was the issue.
