That’s my gut feeling, that writing fast C# basically ends up looking like C++/Rust/etc where the niceties of C# are no longer present.
Which is the same as rewriting Python in cython. It’s way faster, and it doesn’t look like Python, or have the benefits of Python, and now just looks like weird C.
Most common optimization path is simply removing the junk and making the code drastically simpler, using appropriate CoreLib APIs and similar. A C family language that looks like other C family languages, very surprising.
Is there something specific you would like to see an example for?
