title: VS2013 Update 3 incredibly slow - devenv.exe!!IsAssertEtwEnabled guilty thread
body: <p>VS2013 Update 3 is incredibly slow and I'm tearing my hair out. </p>
  
  <p>From Process Explorer, it looks like IsAssertEtwEnabled is having fun with my CPU and al;so there is a lot of file access going on.</p>
  
  <p>What does IsAssertEtwEnabled do and what could cause this?</p>
  
  <p>Oh, and in safe mode everything works fine. But I have disabled all the extensions I can without uninstalling and it's still dead slow.</p>
  
  <p>Cheers,</p>
