Tokio LIFO slot latency bound: missing configuration for tail-latency control
Scheduler behavior under sustained concurrency Tokio's per-worker LIFO slot optimizes throughput by keeping recently yielded tasks on the same worker, reducing cache misses for bursty workloads. Under sustained high concurrency, however, tasks that repeatedly yield can monopolize the slot, starving other ready tasks that remain in the global FIFO queue. This
