Now that all tasklet queues are scanned at once by run_tasks_from_lists(), it becomes possible to always check for lower priority classes and jump back to them when they exist. This patch adds tune.sched.low-latency global setting to enable this behavior. What it does is stick to the lowest ranked priority list in which tasks are still present with an available budget, and leave the loop to refill the tasklet lists if the trees got new tasks or if new work arrived into the shared urgent queue. Doing so allows to cut the latency in half when running with extremely deep run queues (10k-100k), thus allowing forwarding of small and large objects to coexist better. It remains off by default since it does have a small impact on large traffic by default (shorter batches). |
