Cool asymmetric network performance happened to mess up a customer benchmark

A bunch of Unison systems, a 40 GbE network interconnecting them, and a bunch of client nodes on 40GbE -> 4x 10GbE links (to accomodate enough clients for the load testing). 40GbE < -> 40GbE works great. Full bandwidth, only minor oddities (single thread performance around 27Gb/s, need multiple threads to hit 40). 10GbE < ...
