I don't know, I've got two panes here opened next to each other (tiled/xmonad) with xterm and alacritty, and I've been typing in those for the last 5min, and I really can't tell the difference (my monitor has 5ms latency).

Does it have 5ms response time or "input lag" because both are very very different and input lag isn't a spec you'll find on the box.

You typically need special hardware to measure it, or find review sites that go out of their way to cover it.
