title: TFS 2012 API - .GetService<WorkItemStore>() Slow
body: <p>I have a custom web service using the TFS API installed on a TFS 2012 server.  After upgrading the TFS server from 2010 to 2012, the following line of code is taking 20 to 30 seconds to execute for my users with every call to the service:</p>
  
  <p>WorkItemStore store = tfsCollection.GetService();</p>
  
  <p>Before the upgrade, the performance for this web service was fine.</p>
  
  <p>Has anyone experienced a performance problem with the TFS 2012 API like this?  Does anyone have a suggestion to resolve this performance issue?</p>
  
  <p>I do have the cache setting WorkItemTrackingCacheRoot configured.</p>
