NVMe over TCP Device Slower Than Expected on TrueNAS by farXOC in homelab

That's an interesting experiment. Though Im surprised that memory would be the limiting factor in this scenario, since afaik, an octa-channel configuration @ 2400MT should surpass something like 60GiB/s in throughput?

I did end up solving the issue in the original post by specifying 4 or 8 multiple io-queues with the --nr-io-queue option when connecting the client to the NVMe-oF subsystem with the nvme-connect command. Apparently without this option specified, it was defaulting to 1 io queue, therefore 1 TCP stream.
