The "proprietary" .NET was very performant. It's the new "open" one that has to catch up.

You have posted something along these lines twice, it is not correct. .NET Core has been better performing than Framework from the start. You may be thinking of Mono.

Just an aside: Thanks for using "better performing" and not the non-existent word "performant." ;)

.NET Core isn't based on Mono.
