alt Hacker News> What exactly do you need 1ms instead of 14ms startup time in a shell startup?
I think as they said: when dynamically building a shell input prompt it starts to become very noticable if you have like 3 or more of these and you use the terminal a lot.
Ah, I only noticed the "shell startup" bit.
Yes, after 2-3 I agree you'd start to notice if you were really fast. I suppose at that point I'd just have Gemini rewrite the prompt-building commands in Rust (it's quite good at that) or merge all the prompt-building commands into a single one (to amortize the startup cost).
