ZFS should absolutely be able to go faster even with lz4 compression I get writes above 5 GB/s on a older 32-core EPYC CPU. And that is with mostly random and already compressed data. And that write speed is a limitation of the RAIDz2 on top of not the fastest drives (6 PCIe 3.0 intel U.2 ones from 2 years ago).
