ECN should be enabled irrespective of the current bottleneck bandwidth. I don't see any relationship between serialization delay with ECN. Congestion control is about determining the right amount of inflight data. ECN just provides an explicit congestion signal as feedback and helps anyway. The main problem is IMHO that most routers have no AQM in place in order to set the CE codepoint appropriately...
