It’s fast. In the same league as Alacritty and Wezterm, which is to say on the doom fire benchmark those terminals can do 500fps plus, where iTerm2 does 90fps on my M4 MacBook Pro. In practical terms if you use tmux or vim in the terminal, it makes a big difference for typing latency and scrolling.

Thank you! Interesting, because I haven't perceived "terminal performance" as a problem before. I will try it out

The parent is probably referring to this benchmark: https://github.com/const-void/DOOM-fire-zig/

Where should I look first if I only get around 160 fps, while WezTerm gets 400+ fps?

I am not a very adept terminal user. I just hook in to tmux. So all emulators are basically the same for me. Switching windows in tmux is much faster than clicking on tabs. ghostty at least looks much nicer. It has a lot of built in fonts and themes. Command line editing is similar. Man pages for some reason are very slow to open in iterm2, but that isn't the case here. The only deal breaker for me is that it takes up a lot of cpu (in macbook air). Unless there is a simple, non-consequential config to change that will fix this, I will stay with iterm for now.

> Switching windows in tmux is much faster than clicking on tabs.

Sure, if you're clicking tabs... A fairer comparison would be between the keyboard shortcut to switch windows in tmux and the native keyboard shortcut to switch tabs.

which is prefix+number in tmux. I don't know if you can easily jump to a tab with a visible index in ghostty.

On Mac at least it seems to be cmd+number

I tried it but I just can't jump since it doesn't have support the global hotkey to autofocus iterm that I'm so used to.

I tried using their toggle_visibility keybind but it's a bit wonky since it doesn't return focus back to another window when you toggle away.

I just use rcmd for that. But that iterm feature is nice.
