Yeah I mounted the zpool directly to /mnt like in the first post of this thread.

Thank you for taking time to reply! I know it has been a few days... I stopped caring about ZFS for a while but gave it today another shot with different configs, trying to incorporate your tips and also did some more research. I also stopped caring about that benchmark, I just used it as it was more or less comparable to my setup. Having said that, I of course "benchmarked" it, but just by samba file transferring and running VMs on it and stuff. Samba maxxed out at about 90MB/s (or about 750Mbit/s) which is still a bit slower than hoped for. Realistically it's fast enough, but still noticeably slower than a normal unraid+cache setup. Also getting samba to work, I tried the symlink approach, has been quite annoying as often I would get errors about permissions. Maybe I try truenas after my vacation which should be more guided in setup and see if maybe I still did something wrong somewhere.

Thank you for your reply! Time zones are just a social construct, I'm sure we would manage somehow if needed. I also had a feeling the test might be weird, but the idea for me at least was: He has this and that performance with that settings, so I should be around there as well. Wendell has bigger disks (but same amount) and who knows about the rest of the system, but he claims with the same test command ~160MB/s while I was around 20. Of course with the same ZFS settings. Not sure how to test the performance better and how to compare it.

Sorry I didn't see the message, but I really appreciate the offer. In the meantime I did some progress already and I think at least one issue is my CPU performance, as it doesn't boost as high as it could. Performance increased a lot with the cpu governor on performance, but still slower than I would expect. I will try around a bit more and would possibly come back to your offer. Another comment had the valid complain that I didn't provide much information so here it goes: It's a Ryzen 7 5700G system with 32GB DDR4 4x4TB Seagate IronWolfs on a LSI Broadcom 9201-8i HBA I tried Raid-Z1 and 2x 2 drive mirrors. In general I basically followed the guide on level1techs forum for the general zpool, dataset and test command.

I finally tried this plugin and set everything up, 3x 4TB hdds with a raidz1 and I did run a command to test the speed from level1techs forum and I have abysmal performance. I get around 20MB/s read and writes, not sure how to troubleshoot this. In the example given in the forum he had around 150MB/s with 4 8TB hdds The command is: fio --direct=1 --name=test --bs=256k --filename=/dumpster/test/whatever.tmp --size=32G --iodepth=64 --readwrite=randrw

is there a reason some default settings like the interface and advanced dns settings have been changed? Especially the "permit all origins"?
