[zeromq-dev] Ultra low-latency timings

Have a source for this now: from the mechanical sympathy blog, 1µs for
InfiniBand and 5µs for Mellanox/Solarflare user-space IP with RDMA 10GigE.

My current standing is that IB is always a fraction faster than Ethernet
but only by 1-2 generations and requires a complete new expensive
infrastructure replacement on each IB multiplier boost.  Ethernet
definitely seems the way forward but isn't the top position.
