Hmm 🤔❓... Lets say there are identical nodes A & B mining at the same difficulty. A is hashing a block of size 0.1MB, and B is hashing a block of size 8MB. Will node's A hash-rate be noticeably higher than B's?
No, they're hashing a hash/header of the block, so the size of the block is largely immaterial to the speed of the hashing.
