What kind of enhancement you would like to have? Please describe.
This is a performance improvement request.

Describe the enhancement you'd like
Crc32Computer checks CPU architecture for every byte. Reduce the unnecessary conditional CPU instructions.

commented

maybe we need XXHash will be better ? (in .net XXHash will come in .net 8.0 )

We use CPU instructions to calculate Crc32. I am not sure if it would make a difference.

You are right, crc32 can get hardware acceleration.
