Another look at terminal emulators

I had some time this weekend to look back at my frametime project from last year. Drawing inspiration from an article on lwn from 2018 called A look at terminal emulators I figured it could be fun to dive into the relative performance of terminal emulators is 2022.

The lwn article used an application called Typometer to asses the relative latency of the different terminal emulators. Typometer works by sending some input to the application, and monitoring the display buffer until the change is reflected. Assuming the other parts of the chain are unaffected by HOW this change comes to be, it’s a really simple pure software solution to getting a latency number.
