2 years ago Looking through the various issues, several of them identify what I am experiencing but I think this one is probably the best place for me to follow on.
Just to be sure it wasn't a broader problem, I did this. Still, no luck.
To validate the issue, I tested the plugin loading times using the "A Note on Profiling with zsh/zprof" section of this article. The results I got were pretty surprising.
This first test was what I was initially dealing with:
num calls time self name

1) 1 16982.97 16982.97 65.03% 16982.71 16982.71 65.03% _zsh_nvm_auto_use
2) 2 6257.87 3128.93 23.96% 3328.52 1664.26 12.75% nvm
3) 1 2835.52 2835.52 10.86% 2772.00 2772.00 10.61% nvm_ensure_version_installed

10) 2 21.66 10.83 0.08% 21.66 10.83 0.08% compaudi
...Then, I set NVM_AUTO_USE=false. This was the improvement I saw:

...Finally, I deleted zsh-nvm from the list of plugins in my .zshrc and it became obvious that zsh-nvm is what is killing my load times:

Hi everybody,
I have had this problem for some time now and didn't find a solution, so I hope you guys can help me out. When I use
zsh-nvmwithout lazy load, the session start takes insanely long (~30 seconds). That startup is only that slow when I open Terminal the first time after a restart of the machine. When I use lazy loading,.nvmrcfiles are ignored until I manually enter something likenvm -vand thencdin the corresponding folder.EDIT: I just saw that you wrote about this in the README: https://github.com/lukechilds/zsh-nvm#auto-use
I tried to fix it according to issue #28 but adding PATH before zsh-nvm didn't change anything.
gives me
yepI don't know what I should look for or what the culprit could be. I hope you guys can give me some tips on where to look!
