Cleaning up Inside Meshes - Speedup Contest

I enabled optimization according to your instructions and it’s really a speed up of ~4x. Very nice.

But when I compiled the same code in VS2022 I’m back at ~20sec. Is there anything I can do to speed up the std VS2022 compiler?

(My own DLL Library is .NET Framework 4.8, and I’m still mainly using R7)
