Mine takes 50ms, assuming wsl is hot (recorded screen and compared mouse click frame to window pop up frame). I think op should try a different wsl distro or a blank machine and compare differences. I have on access scanning off, performance on, Ubuntu wsl distro, and windows 10.

I believe OP recorded him pressing a key on keyboard and counted between key is clearly pressed and the moment when xterm is up.

Compare to screen recording, this adds latency introduced by keyboard and monitor, which sometimes could be 100ms+. See https://danluu.com/input-lag/
