I'm fairly confident you are victim of a PMTUD black hole. It's easily fixed by making your router force the TCP MSS to a slightly lower value. All your symptoms are explained by this (some but not all devices are affected, some

For reference, my server CPU is an AMD Ryzen 7 PRO 5750G (65W TDP, 3.8-4.6GHz, 8-core, 16-threads) and CPU usage is around 8% when writing at 700 MB/s on my raidz2. In other words, only a little more than 1 of the 16 hardware threads i
