zfs conceptually chops the data into recordsize chunks, then compresses
each chunk independently, allocating on disk only the space needed to
store each compressed block.
On average, I'd expect to get a better compression ratio with a larger
block size since typical compression algorithms will have more chance to
find redundancy in a larger block of text.
as always your mileage may vary.
