title: IIS and Coldfusion concurrent requests limit
body: <p>I am using IIS and JRun to serve coldfusion application.  </p>
  
  <p>Something is limiting maximum number of concurrent connections - they never get above 25.  </p>
  
  <p>My application is waiting for response from external services for long time and could possibly handle much more concurrent requests.</p>
  
  <p>I've found only one value that may have something to do with this:<br>
  In <code>jrun.xml</code> <code>activeHandlerThreads</code> is set to <code>100</code></p>
