I usedfeeltty to measure the interactivity of a Coder SSH session vs. SSH directly into the box.

Coder is substantially slower in ourcoder-ts (Docker-based) template. I get baseline latencies in my AWS workspace.

$ feeltty ssh coder.pollconnect              2990.36792msinput sample size    32input mean           118.698msinput stddev         274.132ms

$ feeltty ssh <redacted>connect              1199.80383msinput sample size    32input mean           55.526msinput stddev         43.138ms

Oddly, I see equal throughputs as tested byssh <host> -- cat /dev/urandom | pv > /dev/null.

Perhaps#3505 will fix this. (cc@kylecarbs,@bpmct)
