title: Visual Studio Build Very Slow
body: <p>This applies to both 2008 and 2010 versions (and probably earlier ones too).  Also to both C++ and C# projects.</p>
  
  <p>An initial build (after reboot) runs at normal speed and with reasonably good CPU utilisation.  After "some time" (ie using the computer for "stuff"), a subsequent build might run very, very slowly and with very <em>low</em> CPU utilisation.  The only fix I have found seems to be a reboot, then the cycle starts all over again.  This happens on both WPF and non-WPF projects, though it's 10 times worse with WPF.  </p>
  
  <p>This has happened to me on different machines, even working for different organisations, so I think it's a Visual Studio thing, not an environment thing.  I've tried the usual (Google, turn off AV, Intellisense, Resharper etc, and currently looking forward to getting the SSD I have on order).</p>
  
  <p>My current machine spec is 2.7gig quad core, 4GB RAM, XP (haven't got Win7 at work yet), 250Gb hdd etc</p>
  
  <p>Anyone got any ideas what this could be and how to fix it?</p>
  
  <p>Thanks in advance!</p>
