I am curious to see benchmark results for the same use cases but with 10ms and 100ms latency added between the client and server. It looks like the bench currently just stays within the same machine.

I do not often operate below application layer, but as I understand it both the HTTP and SSH layers would add back-and-forths from client to server that UDP does not perform. Would UDP over HTTP over SSH have a slowdown steeply (but linearly?) correlated with the ping to the server? And (>linear) increased effects on packet loss? Crowbar seems to only do HTTP, so saves some considerable amount of backs-and-forths... but doesn't have the benefit from websockets...
