title: Poor VS Performance - High CPU on IsAssertEtwEnabled
body: <p>I'm running Visual Studio 2013 Update 4 and have been seeing high CPU usages and noticeable delay on simple UI menu navigation and basic text editing.</p>
  
  <p>Using <a href="https://technet.microsoft.com/en-us/sysinternals/bb896653.aspx" rel="noreferrer">ProcessExplorer</a> I took a screenshot which shows one thread is doing a lot of CPU in something called <strong>IsAssertEtwEnabled</strong>:</p>
  
  <p><img src="https://i.stack.imgur.com/ULytx.png" alt="Process Explorer Screenshot"></p>
  
  <p>The screenshot was captured randomly scrolling up and down in the Extensions and Updates window.</p>
  
  <blockquote>
    <p>Any ideas how to speed up performance?</p>
  </blockquote>
  
  <p>And yes I'm running several plugins, but I'd prefer to keep them, or at least find a way to isolate which one is causing this.</p>
  
  <p>And I've reviewed a similar issue (<a href="https://stackoverflow.com/questions/26220685/vs2013-update-3-incredibly-slow-devenv-exeisassertetwenabled-guilty-thread">VS2013 Update 3 incredibly slow - devenv.exe!!IsAssertEtwEnabled guilty thread</a>), but I don't have anything from DevExpress installed.</p>
