Interestingly, early Ethernet performance studies suggested that about 37% utilisation was the best possible on a heavily contended network due to all the collisions. So a 10mbps Ethernet cable run was arguably similar in performance to 4mbps TR? That was essentially IBM's marketing argument for 4mbps token ring. But TR was more predictable under heavy traffic contention. That’s what we were told anyway…
