[Solved] oh-my-zsh slow, but only for certain Git repo (2023)

git zsh

Solution 1

You can add this to your git config and zsh won't check the status anymore

git config --add oh-my-zsh.hide-status 1git config --add oh-my-zsh.hide-dirty 1

Explanation

There are two central git functions in in lib/git.zsh:

git_prompt_info()
parse_git_dirty()

Each Method has a git config switch to disable it:

oh-my-zsh.hide-status
oh-my-zsh.hide-dirty

Some themes create their own git queries and sometimes ignore these flags.

Solution 2

Oh_my_zsh seems to be slow for some repos because it checks the status of the repo after each command.This behaviour can be overridden in the new version of .oh_my_zsh .Just Uncomment the following line in .zshrc:

DISABLE_UNTRACKED_FILES_DIRTY="true"

After this, restart your terminal or run the following:

source ~/.zshrc

Solution 3

For me it's slow on VirtualBox (the guest) because I'm using a synced folder. I still want it enabled on OS X (the host) where it's fast enough. Instead of using a local config setting which is stored with the repo and would change it both on the guest and host, I use a global config setting only on the guest:

git config --global --add oh-my-zsh.hide-dirty 1

If I want it just for a single repo:

git config --add oh-my-zsh.hide-dirty 1

Solution 4

It could be the theme calling git and rvm stuff after every command.

For me, changing ZSH_THEME="juanghurtadoto" to ZSH_THEME="miloshadzic" removed the 2 second delay after every command completely.

Themes can be found at https://github.com/robbyrussell/oh-my-zsh/wiki/themes

Solution 5

There are various way to speed up an oh-my-zsh, as detailed in "zsh starts incredibly slowly", cleaning up the plugin section.

For instance, the blog post "Fix for oh-my-zsh git-svn prompt slowness" mentions the parse_git_dirty function as a potential issue.

I recently started using Zsh and it's awesome. Unfortunately, for the project I consider my "main" project, everything is slow. What I mean is that every time I run a command - ls, for example - there's about a five-second delay between the time the command is executed and the time I can use the terminal again.
What could be different about this one repo that makes Zsh so slow? I assume it's a Zsh-specific thing because there was no problem before I started using Zsh. I tried doing a git clean but it didn't make any noticeable difference.
I'm on Mac OS X if that matters.
Update: Turns out this line of my .zshenv is what was making it slow:
```
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
```
If I comment that line, it goes from taking about 3 seconds to taking about 1 second. Unfortunately, I need that line, since many of my projects use RVM. I don't know what to do now.
Update 2: this seems to be specifically an oh-my-zsh thing. If I don't load ~/.oh-my-zsh/oh-my-zsh.sh, I don't have a problem.

  and if you use bash now, is it still slow?

  Excellent question. No, it's fast on bash.

  Is it still slow if you move your ~/.z* files out of the way?
- Jason Swett over 10 years
  
  No. So I guess it's something in one of those.

  Okay, the culprit seems to be ~/.oh-my-zsh/oh-my-zsh.sh. I don't know what to do with this information, though.

  Narrowed it down even further and updated my answer.

  Also, when I include oh-my-zsh.sh in my .zshrc, it for some reason loads .zshenv twice, which loads RVM twice, which must certainly make things slower than necessary.

  If the repo is big, calling git st everytime might slow the shell down. Use this option to turn it off. git config --add oh-my-zsh.hide-status 1

  FYI this also occurs on WSL on Windows with Oh My Zsh.

That stuff helped in that it led me to start commenting stuff out to see what might make things load faster. I narrowed the problem down further and updated my question.

Interesting. +1. This is more specific than my answer.

The compinit post improved a small amount for me, but removing parse_git_dirty really sped things up. Thanks.

This solution still works, just tried this in my Symfony2 project folder. Maybe the vendor folder makes things slow, like the rake folder does for rails apps? zsh is fast now, and I do not need the GIT zsh plugin anyway. Thanks!

This solved my problem perfectly. I can still use the nice git-status business in other repos, but not in my huge firefox source code repo where git it slow.

git config --add oh-my-zsh.hide-status 1 speeds the things up but it completely removes the zsh status of the VCS. This one keeps it and still speeds it up.

I had to use oh-my-zsh.hide-dirty. It might have changed or maybe my theme (agnoster) only respects hide-dirty.
Bruno Buccolo over 6 years

Don't forget to update oh-my-zsh, otherwise your lib/git.zsh might completely ignore the hide-dirty option.

Doing this in global settings for vagrant virtualbox vms with --global is really handy (slow in guest, fast on host) as described here: stackoverflow.com/a/40943155/1092815 <3

Neither this nor the solution below help speed things up for me. Any ideas? git status is definitely the slow issue

git config --add oh-my-zsh.hide-dirty 1 was all I needed for my slow repo.
Johnathan Elmore over 3 years

I was hoping this would do the trick, but no effect, even after source ~/.zshrc. git config --add oh-my-zsh.hide-dirty 1 worked for me, though. git config --global --add oh-my-zsh.hide-dirty 1 to disable this for all repos.

@JohnathanElmore @Peeyush, DISABLE_UNTRACKED_FILES_DIRTY="true" doesn't do the same thing as the oh-my-zsh.hide-dirty setting, even though they're similar. See the code here: github.com/ohmyzsh/ohmyzsh/blob/master/lib/git.zsh#L17. The DISABLE_UNTRACKED_FILES_DIRTY setting simply adds an --untracked-files=no flag to the git status command, whereas the oh-my-zsh.hide-dirty 1 setting will skip the whole git status command altogether. I recommend @JohnathanElmore's suggestion of the global git config setting.

A few notes about this solution: I also needed to remove git-prompt from my list of plugins and completely launch a new shell before things improved. (Despite the name, that plugin isn't required for git info in your prompt at all.) Just sourcing .zshrc wasn't enough. Also FWIW, the takashiyoshida theme works great with these flags.

git config --global --add oh-my-zsh.hide-dirty 1 I add this config to the global config. speeds up a lot
