title: Why is my Test View in Visual Studio so slow?
body: <p>I have VS 2010 Ultimate with ReSharper, Reflector, and SpecFlow extensions. I use SpecFlow in one of my test projects along with WebDriver for automated UI testing. I am now approaching about 400 individual test scenarios in that project.</p>
  
  <p>When I open Visual Studio, everything is fine (aside from some of the usual synchronizing slowness that comes with ReSharper). However as soon as I click the tab to show my built-in "Test View", VS freezes up for about 60 seconds while the tests load.</p>
  
  <p>I'm concerned this is going to get worse as we put more tests into the SpecFlow project. Is there anything I can change in my TestSettings file to make this go faster? Should I try and ditch the TestSettings file altogether, or is this not even possible? Or, should I switch from using MSTest with SpecFlow to something else like NUnit, to make the Test View slowness go away?</p>
