Whenever I read about those yearly performance improvements, I wonder if there are some real world benchmarks. Some applications that were benchmarked on all .NET versions up from Framework 4.7 as a baseline. And all the .NET versions since as a comparison.
That's impressive, considering a major release is sniped every year. I've never thought it would be that much of an improvement outside of synthetic benchmarks.
Managed devs have been begging for such fixes since the start, so many important perf gains were just left on the table at the same time we were being given the message that C++ and Javascript was the future. My exposure to it at MS was during the Win vs Dev Div conflict (the Steve Sinofsky / Steve Balmer era) and the message that managed software was slow was a core part of that battle.
