Starship: A minimal, fast, and customizable prompt for any shell

Does the speed of your shell matter? Surely the speed of the programs that you're running through your shell matter more. I've never been let down by how fast bash can tell a program to start running

EDIT: oh, i misunderstood, its just the prompt at the start of your shell... I dont think ive ever been annoyed at how fast that renders either

Some people like to put, for example, their current git branch in the prompt. To get that means at least naively, running a git command on every single line the prompt renders on. Git is fast, but it's easy to add a bunch of these and suddenly your prompt takes 100ms to render. Hit enter a few times and you'll immediately notice lag. For that reason, doing this fast does make a real difference.

Of course the fastest thing is to just not stuff your prompt full of detail.
