I was skeptical of the claim that it's faster than traditional SSH, but the README specifies that it is faster at establishing a connection, and that active connections are the same speed. That makes a lot of sense and seems like a reasonable claim to make.

Although, dollars-to-donuts my bet is that this tool/protocol is much faster than SSH over high-latency links, simply by virtue of using UDP. Not waiting for ack's before sending more data might be a significant boost for things like scp'ing large files from part of the world to the another.

That's why mosh exists, as it is purpose built for terminals over high latency / high packet loss links.

But mosh doesn't actually do any of what ssh does, let alone do it faster - it wins by changing the problem, to the vastly narrower one of "getting characters in front of human eyeballs". (Which is amazing if that's what you were trying to do - but that has nothing to do with multiple data streams...)

mosh is hard to get into. There are many subtle bugs; a random sample that I ran into is that it fails to connect when the LC_ALL variables diverge between the client and the server[0]. On top of it, development seems abandoned. Finally, when running a terminal multiplexer, the predictive system breaks the panes, which is distracting.
