GitHub - jimblandy/context-switch: Comparison of Rust async and Linux thread context switch time.

These are a few programs that try to measure context switch time and task memory use in various ways. In summary: A context switch takes around 0.2µs between async tasks, versus 1.7µs between kernel threads. But this advantage goes away if the context switch is due to I/O readiness: both converge to 1.7µs. The async advantage also goes away in our microbenchmark if the program is pinned to a singl

Rust asyncとLinuxスレッドの、コンテキストスイッチ時間とメモリ使用の比較。スイッチ時間は、async task間が0.2μs、カーネルスレッド間が1.7μsとのこと。
