The current implementation uses a lot of bytestring slicing. While it is much better than the 3.10 and earlier implementations, it can still be further improved by using memoryviews instead.

Possibly. I will check this out.

Tried and failed. It seems that the overhead of creating a new memoryview object beats the performance gained by it.
