How to fix slow zsh shell startup

My ZSH shell startup is super slow, it is getting frustrating opening a new shell to run some command, so let's try to fix it.
Also, what is the subscriber initiative?

Who was the man who hijacked my left headphone speaker at the end? The brother of Michael MJD and FitMC?

[@DaneHarnettDevs]

Was it Rick Murray - Head of Engineering?

[@nathanbrennan4011]

Nice optimisation. Need more of this in my life. ♥️👌

[@DaneHarnettDevs]

Yeah it was a big jump! I’ve spent a bit more time on it and it’s so much nicer now too

Welcome back to youtube

[@DaneHarnettDevs]

Thank you!

[@tldyesterday]

[@DaneHarnettDevs]

Glad I could help!

What i did is that i downloaded the nvm plugin folder from "oh my zsh" then i added the line "zstyle ':omz:plugins:nvm' lazy yes" to enable lazy loading for the plugin and sourced the plugin (has to be after compinit) It doesn't even need use the "oh my zsh" 'framework'. I get 0.01s system time

[@DaneHarnettDevs]

Nice! That’s a good solution too

[@diegoulloao]

zsh --interactive -c exit 0.42s user 0.53s system 5% cpu 15.970 total

[@DaneHarnettDevs]

Nice!

[@romanstingler435]

as a Linux user on a notebook with 0.09s to execute zsh I am laughing and wondering if you download zsh from git every time you open it (just an exaggeration)

[@DaneHarnettDevs]

Yeah it’s pretty crazy isn’t it! I’ve made further changes after this and have it faster again but not as fast as 0.09s yet. Do you have your config online so I can compare?

[@taharlaaroussi7875]

Nice, thx

[@DaneHarnettDevs]

You’re welcome! 😊

[@ryanaiden]

That initial wasn't an exaggeration... I've seen and had longer load times because of eks and all the rest bundled in 1 terminal 😅

[@DaneHarnettDevs]

It’s painful isn’t it!

[@ryanaiden]

@@DaneHarnettDevs yea it sucks. one has to have separate envs/terminals if you want close to instant startups haha

[@ditchcomfort]

Just to let you know all the $(brew - -prefix) also take some time. So perhaps consider using a full path instead. And, I have to be honest, even though yours isn’t the worst I’ve seen, Oh My Zsh isn’t the fastest/best framework to use either. You’re probably better of configuring something from scratch. And if you’re not using 10-15 plugins, you absolutely don’t need all the extra bloat, and people trying to sell you T-shirts 😀

[@DaneHarnettDevs]

Thanks! Yeah I’ve switched from OMZ to antidote now and made it much faster
