I am in the same school of thought as you, fair queuing is the most optimal solution while capacity is constrained. This is the approach we took in Aperture, an open-source load management system. Read more about our Scheduler which implements a variant of WFQ (Weighted Fair Queuing) to ensure desired capacity allocation across workloads (group of requests at the same priority level) and SWFQ (Stochastic Weighted Fair Queuing) to ensure fairness across users within each workload: https://docs.fluxninja.com/concepts/scheduler https://docs.fluxninja.com/concepts/scheduler
