title: Why does WCF limit concurrent connections to 5?
body: <p>I have a WCF service (basicHttpBinding) hosted in II7 on Vista that I expect to handle many requests concurrently.  I'm attempting to load test the service by spawing 200 threads in a test app and calling the WCF service.  I've run this test app on the same machine as the server as well as multiple other computers and I always get the same result - no more than 5 workers are used.  Is this a WCF, HTTP or IIS bottleneck?</p>
