title: Slow git autocomplete with WSL2 and zsh
body: <p>I recently switched from git bash on windows to using WSL2 almost exclusively.</p>
  <p>The issue I am having is that my tab autocompletes for branches is insanely slow (in the seconds). Other autocomplete are fast, such as autocompleting git commands (git checko[TAB] would autocomplete to checkout without problem).</p>
  <p>What can I do to isolate the problem or resolve ( less than 1 second to autocomplete) it?</p>
