This article raises interesting questions. He has done low-level tests which do not read much from the data or instruction pipelines, so these tests show compiled MSIL can be better optimized than C++. C++ is prone to accidental performance deficits from problems like aliasing, so that makes sense.

Now I want to see higher-level tests, where algorithms reading significant data or application-level benchmarks are run. The faster the CPU core, the less penalty there will be from C# compilation. The problem is that it would take lots of time to translate something like WORF, GAMESS, or other standard numerical benchmarks.
