title: emacs find file in project on a big project
body: <p>In vim, there is this amazing plugin called command-t, that lets you fuzzy-search through all the files in your project. We have a fairly large rails app with a ton of files, and it is able to handle it pretty much without any slowdown at all.</p>
  
  <p>tried a few things (like ffip, textmate.el's command-t, and rinari's rinari-find-in-project). The UI is great (I &lt;3 flex), but the problem they all have is on a large project, the performance is bad to the point of being unusable.</p>
  
  <p>Currently I am making more use of rinaris navigation commands and ido-find-file. Between the two of them it is a usable setup, but it would be nice to have a crazy fast fuzzy find in project.</p>
  
  <p>Does anyone know of a more performant script then what I have tried?</p>
