I can't provide you with numbers but back when I used Windows on my work machine, I recorded my screen + microphone input using OBS to compare they recorded keystroke sound and appearance of the character on my screen. I was able to confirm my suspicion in that WezTerm yielded higher input latency. This was especially noticeable when using helix inside of WSL - movement in normal mode would always sort of lag behind the keystrokes.

EDIT: Just installed in on my Mac and here, I can't notice any difference between kitty (my current input latency baseline) and WezTerm. Good stuff! Not sure how Windows fares nowadays, though.

I don’t know if it’s my setup or just Windows quirks but even Alacritty feels slower than Windows Terminal.

You can also use Is It Snappy? from the App Store to test typing latency. It was made by Chad Austin who had problems similar to us.
