Average throughput per SS for the BE class. LAWRR is better than WRR for 0 to 20 SSs but performs similarly from 20 to 35 SSs because no packets are allowed to be transmitted. The reason for the superior performance of LAWRR here is the opportunity given to the BE class when traffic is light and its service round is proportional to the traffic load characteristics of each queue, which yields an increase in the number of packets transmitted in a round.
