A very long time ago (2003) the CLR Performance Team published an article authored by Jan Grey called "Writing Faster Managed Code: Know What Things Cost". In the ten years since this was written .NET has had many more basic operations added; and I'm sure the performance of many of the basic operations referenced in the article have changed since the original release of the CLR.
Is there a good reference out there that has updated performance measurement for basic operations for more recent versions of the CLR?
