> AVX instructions, which is implemented for quite a few LINQ methods
Are you sure? Any examples of such methods? And does AVX actually helps?
I don’t think that’s possible because IMO AVX and other SIMD can only help for dense inputs. The C# type is ReadOnlySpan, however ReadOnlySpan doesn’t implement IEnumerable and therefore incompatible with LINQ.
There’s even an alternative LINQ to workaround https://github.com/NetFabric/NetFabric.Hyperlinq but that thing is a third-party library most people aren’t using.
