not the same person but in the flow of doing things those little pauses (tens of milliseconds) do matter. I open/close nvim (and less-so tmux) a ton, and run lots of commands per day. I don’t want to wait

and once you get used to things being that fast, it’s hard to go back (analogous to what people say about high-refresh screens/monitors)

all that said the speed of the default mac terminal (and other emulators I tried) was always fine for me, performance was not why I switched to Ghostty
