A while back, Jose blogged about the CPU throttling feature in ASP.NET 4.5 . As described in the original post, this feature is intended to correct negative scaling in server throughput when handling async requests on a server with saturated CPU. Now, for the next chapter to this story: CPU throttling under stress scenarios. This feature was tested during development in the ASP.NET performance lab. Performance testing, unlike stress, tends to be very homogenous: measure server throughput under full load (CPU) when handling a specific scenario or request. When this feature entered the stress lab, it encountered more real-world applications: longer run times, various requests and bursty traffic. Under these conditions it became clear that CPU...(read more)
