title: ctrlp :CtrlPTag search slow
body: <p>Im using ctrlp.vim and I'm trying to use the <code>:CtrlPTag</code> feature. I setup ctags using the instructions from this blog post:</p>

  <p>I've generated a ctags file for my Rails project and all my bundled gems using:</p>
  
  <pre><code>ctags -R --languages=ruby --exclude=.git --exclude=log . $(bundle list --paths)
  </code></pre>
  
  <p>The ctags file is about 13 MB.</p>
  
  <p>When I try to run <code>:CtrlPTag</code> and just search for methods the search is very slow. Trying to type and delete the search text almost hangs vim completely. </p>
  
  <p>Does anyone have any suggestions to speed up <code>:CtrlPTag</code>?</p>
  
  <p>Note: I have tried to setup vimgrep to use 'ag' thinking that would be faster, but that hasn't helped.

  <p>Thanks for the help!</p>
