> 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.

Project mention: Last Week of Hacktoberfest | dev.to | 2023-10-27

I kicked off my Hacktoberfest contributions by diving into CrispyWaffle, a project that caught my attention due to its importance in the .NET ecosystem. The maintainers had an open issue #211, which required assistance in removing a retry check within one of their classes. After discussing the changes and receiving their initial approval, they encouraged me to seek additional areas for improvement within the codebase. Eager to make a positive impact, I accepted the challenge.
