Pingora tokio runtime.
Tokio runtime comes in two flavors: a single-threaded runtime and a multi-threaded one which provides work stealing. Benchmark shows that, compared to the single-threaded runtime, the multi-threaded one has some overhead due to its more sophisticated work steal scheduling.
This crate provides a third flavor: a multi-threaded runtime without work stealing. This flavor is as efficient as the single-threaded runtime while allows the async program to use multiple cores.
