Possibly RDMA over thunderbolt. But for RoCE (RDMA over converged Ethernet) obviously not because it's sitting on top of Ethernet. Now that could still have a higher throughput when you factor in CPU time to run custom protocols that smart NICs could just DMA instead, but the overhead is still definitively higher

what do you think "ethernet's overhead" is?

Header and FCS, interpacket gap, and preamble. What do you think "Ethernet overhead" is?

I've meant in usec, sorry if that wasn't clear, given that the discussion that I've replied was about rpc latency.
