A system includes determination of a respective performance level associated with each of a plurality of endpoints assigned to a first routing pipeline, determination of a slow one of the plurality of endpoints based on the respective performance levels, and, in response to the determination of the slow one of the plurality of endpoints, instantiation of a second routing pipeline and assignment of the slow one of the plurality of endpoints to the second routing, wherein the first routing pipeline is to receive messages and to route a first plurality of the messages to the plurality of endpoints other than the slow one of the plurality of endpoints, and wherein the second routing pipeline is to receive the messages and to route a second plurality of the messages to the slow one of the plurality of endpoints.
