Why are you not using Ghostty instead of iTerm2?
Also why would I cat a huge file? That's what less is for. Like wow, in some pretend worse case scenario where you cat out some huge binary file, Ghostty is what, how many ms quicker to paint? Wow! It saved 40MB of memory doing that too, my computer has 16GB I don't care. None of these reasons are very compelling to give up a mature terminal deeply embedded into my workflows, with great tmux integration, and a searchable scrollback buffer.
About to switch to native Terminal.app since it now supports truecolor. Or back to iTerm2.
