title: Measuring CPU load for specific IIS websites on same server
body: <p>I have a IIS server running on Windows Server 2003. The server hosts multiple websites.</p>
  
  <p>Occasionally the CPU load peaks in long durations of time, such that the server stops responding or responds with lag.</p>
  
  <p>The problem is that we don't know which of the multiple websites is creating the high load - I have tried looking around in Performance Monitor for counters which could be used, but I don't see anything about CPU load for specific IIS instances.</p>
  
  <p>This makes it quite hard to find the root of the problem.</p>
