SUMMARY
HTTP traffic simulated by Microsoft Web Application Stress tool, also known as Homer, is not handled equally by all NLB cluster hosts.



MORE INFORMATION
The Microsoft Web Application Stress tool, uses the same source IP address when it simulates each request. When you use Single or Class C Affinity all requests from Homer are handled by a single host in an NLB cluster. The source port is incremented by one for each Get Request Homer simulates. If you configure Affinity to None for the port rules, traffic is evenly distributed across the NLB cluster.
