  Thank you, but are you sure because I know linux does something similar to make sure it is at maximum performance.

    On modern CPUs it doesn’t matter that much. And any optimization would have to be updated for each CPU type (Zen/4, Alder lake, etc.) Modern CPUs have insane out of order execution that makes compiler generated code nearly as fast as the most optimized handwritten ones.

        99% of the time, memory is the bottleneck. It’s why DMA is so huge of a feature.
