title: Emacs creates buffers very slowly
body: <p>On my machine, Emacs takes a long file when creating buffers: when opening the files or directories, or when starting <code>M-x shell</code>.  The pause is 10-15 seconds and is really annoying.</p>
  
  <p>This problem seems to appear when I have about 150+ buffers open (most of them are files and directories on my machine; there are ~5 cmd-backed shell buffers; no remote files).</p>
  
  <p>I have global-auto-revert-mode running on, but the problem persists even with it turned off.</p>
  
  <p>I have this thing, found somewhere on StackOverflow, in <code>.emacs</code>, but it doesn't help:</p>
  
  <pre><code>(setq w32-get-true-file-attributes nil)
  </code></pre>
  
  <p>My environment: Emacs 23.2.1, Windows 7. Do you have any suggestions on what I can try?</p>
