Don’t know about old but definitely not slow. My PC has a ryzen 5 3600 and RTX 3060. All terminals have a fast startup time except for Ghostty.

Ghostty is fast? It takes like 2 full seconds to open and I’m not even exaggerating. Kitty, Alacritty and foot take only a few microseconds to launch. I feel the same in regards to Alacritty, I’d use it as default if it had image support. For now I’m using foot.
