Today I've been visited by kchibisov (Alacritty maintainer) and we've spent several hours benchmarking terminals and editors. 😴
For this test we measured a complex drawing test from vtebench[1]. Key press fills the screen with a complex pattern. I measure the latency from the key press to seeing the pattern at the end of the screen.
Foot ended up firmly ahead, followed by Kitty and Alacritty. Other terminals struggle a bit more with it.
