While micro-optimizations are interesting, there are two questions left unanswered:
- Does this change noticeably affect the total runtime? The checksum seems simple enough that the slight difference here wouldn't show up in PNG benchmarks.
- The proposed solution uses AVX2, which is not currently used in the original codebase. Would any other part of the processing benefit from using newer instructions?
