back in the 2010s I wrote this article medium.com/@jdxcode/12-... which contains an interesting bit on cli perf

<100ms: very fast (sadly, not feasible for scripting languages) 100ms–500ms: fast enough, aim here 500ms-2s: usable, but not going to impress anyone 2s+: languid, users will prefer to avoid your CLI at this point

I largely still agree. I would squibble that "languid" is closer to 1s. I also think there should be another tier for things like `mise env` which need to be <20ms. These are things that you should feel free to put into things like bashrc without noticing delay, even if you do it a couple times.
