i know that there was smartcompression feature in nexenta:
https://openzfs.org/w/images/4/4d/Compression-Saso_Kiselkov.pdf
afaik, it does not exist in zfsonlinux/openzfs.
on my system, i'm getting
- <250MB/s when writing uncompressible data to zfs pool with lz4 enabled
and
- >450MB/s when writing uncompressible data to zfs pool without compression

This is a good article on the subject:

Can't find where the explain it. ZFS magically detects if data is compressible?
Please can someone give me a hint how they do that?
