This might be why, it's using TCP instead of UDP?

    sudo ufw allow 1701/tcp
    sudo ufw allow 9001/tcp

I’m guessing because it’s wireless instead of plugged in. I bet a wired USB TCP connection would be much faster.

Also, if you notice, the laptop response is much faster. To me, this suggests that the drawing on the tablet might require a round trip back to the server. If so, it could probably be sped up by drawing locally/async.
