I know that it has been asked many times, but I was not able to find an answer. Having TrueNAS 13.0-U4 (was updated from 11 > 12 > 13). I have absolutely poor NFS performance on reading. I can never get more than 200/300Mb/s per client (tried with nconnect on 13-U4) even with no load, but surprisingly tried CIFS and can get 1.5-1.8Gb/s per client.

but since my clients only linux boxes, I'd like to keep and maintain NFS as shares. Any ideas what to read / check /fix?

Since I can't reply on many topics, let me post here; hopefully, it will be useful. It seems that in my case turning off all offload functions on the NIC card helps a lot and improves the situation

ifconfig lagg1 -rxcsum -txcsum -tso4 -tso6 -lro -rxcsum6 -txcsum6
