.. for small payloads.

QAT cannot compress across blocks. So as soon as your input is more than 128KB the compression ratio tanks.

Usually well below what even level 1 of software zstd does. They choose the input very carefully.

Interesting. That sounds basically perfect for ZFS where the default is 128KB blocks and zstd compression.
