Not even bad the latency (this is just about latency, not overall bandwidth which reaches the full 4.9Gbit via 2x 2.5Gbit links).

Taken inside a Debian VM running on a Proxmox node connected to the storage:

GMKTec G9 NAS
2x 2.5Gbit
NFS 4.2 (with pNFS)
2x WD Back SN7100 NVMe
Mirror mode ZFS

While this are already pretty awesome latencies, let's see how it performs with SPDK and NVMe-oF (TCP).
