If you experience lagging in some repositories when using the oh-my-zsh shell, then try to hide certain information in the prompt:
git config --add oh-my-zsh.hide-status 1
git config --add oh-my-zsh.hide-dirty 1The status provides information about the current state of the Git repository, such as whether there are any modified files or untracked files.
The dirty information refers to whether there are any changes in the working directory that have not been committed to the Git repository.
