I didn't enjoy the Rust hype on here in years past, but I'm always glad of any better tooling. Just an example from the other week... I swapped out NVM for FNM (Rust) and now I don't have to put up with performance issues, especially slow shell startup times.

Just me being curious since I have used nvm for years without any issues. What do you mean by slow shell startup times? In what way do you use nvm in order to experience any slowness?

I followed the standard nvm install process, to get it loaded from my .zshrc

I noticed a second or two in lag between launching the terminal and getting a shell prompt. Commenting out the nvm load as a test removed the delay. I installed fnm, aliased it to be nvm, and everything is snappy. Also nicer if you use tooling to 'nvm use' when changing into a project directory.

There are a few issue threads such as this one : https://github.com/nvm-sh/nvm/issues/2724

BTW, this blog post was great for finding the culprit if there is zsh startup latency : https://stevenvanbael.com/profiling-zsh-startup
