title: Enable Syntax highlighting in vim on a per-buffer basis
body: <p>I currently have to edit some very large XML files, which slows down syntax highlighting to a point where it's absolutely unusable - it takes multiple seconds to update the screen after a search operation, for example.</p>
  
  <p>When disabling syntax highlighting (<code>:syn off</code>), the same operations happen instantaneously. Unfortunately, disabling syntax highlighting appears to happen globally, so all other files now have it disabled as well.</p>
  
  <p>So: Is there a way to only disable syntax highlighting for a given buffer?</p>
