starvation. Reliable Building on top of Rust, Tokio provides a multi-threaded, work-stealing scheduler. Applications can process hundreds of thousands of requests per second with minimal overhead fine tune to different cases. Flexible Tokio Core Queue-Based Modules in Tokio • Channel • Scheduler • Tokio uses Channel for communication between threads (incl. pthread, co-routines). • Channel From the low level, it is a performant and balanced design with multiple SPSC queues. Key Tokio Scheduler Perf Gap: Synchronization is required for stealing Software Queue Issues Producer Enqueue Software
