title: Speed Increase by Using the Global Assembly Cache
body: <p>If I had a 1000 asp.net websites each with 30 DLL's in their /bin folders.</p>
  
  <p>Therefore 30,000 DLL's.</p>
  
  <p>Would the websites / web server / machine run faster if I registered one set of the DLL's into the Global Assembly Cache and each site used the DLL's in the GAC?</p>
  
  <p>e.g. would the websites collectively use less memory?</p>
