in their README: > Is it really the fastest terminal emulator? Benchmarking terminal emulators is complicated. Alacritty uses vtebench to quantify terminal emulator throughput and manages to consistently score better than the competition using it. If you have found an example where this is not the case, please report a bug. Other aspects like latency or framerate and frame consistency are more difficult to quantify. Some terminal emulators also intentionally slow down to save resources, which might be preferred by some users. If you have doubts about Alacritty's performance or usability, the best way to quantify terminal emulators is always to test them with your specific usecases.
