CPU only reaching 80% (just a point of curiosity)

[matkisson]

So for reference my NAS has a xeon gold 6130, 192GB of ram, a 6x3.2TB RaidZ2 pool for active storage on P4610 drives, and 20x1.92TB SATA drives for archive. Despite different hardware and designs I noticed the CPU utilization when I am pushing a large amount of data to a zstd19 dataset is only 80%. Even with a lower cpu (silver 4110) it was still 80%. Throughput is still good at about 50MBps average. My curiosity is focused on the fact that 80% on a 6130 is a good deal off from adequately utilized. Assuming I disable turbo (which the 80% utilization will still be seen) 13.4Ghz of the CPU is not utilized and idle. I can definitely understand that being a safeguard for less equipped systems but I am curious if there is anything I can adjust that would allow me to increase the utilization to 90%? This systems just needs to be fast while in use and will sit idle most of the time at lower power states. Again this is just curiosity. I have been through the zfs source code and have found points in that which I can adjust but I would prefer to stick with truenas scale and not go in-house.
