Really love to see the fabric better used. PCIe p2p is awesome. Can't wait to see folks playing around with NVMe to GPU, or NIC to GPU, or NIC to NVMe use cases too.

I am a little surprised at the 18.2GB/s speeds. 8 lanes of PCIe 4.0 is 32GB/s. This is pretty far below that. I wonder what could be to blame.
