As I have understood, each limiter acts as a channel with a bandwidth allocated, if within it are created queues, each queue share that bandwidth based on the percentage allocated to each queue or letting pfsense be responsible for rolling, i attached a sample image. if there is only one traffic queues, the entire bandwidth of the limiter is assigned to that queue, if there is traffic in another queue so that traffic is shared among those queues according percent of the queue or you can leave depending on the amount of traffic on queue pfsense decides , that is achieved by letting the percent white. If you think what I said is wrong, please correct me.
