Boost Your Program’s Health by Adding Fibers to your Coroutine
summary
Compares stackless Coroutine TS (co_yield/co_await) and stackful Boost.Coroutine2, then shows integration with Boost.Asio and the Boost.Fiber scheduler. Builds an echo client/server that reads an 8‑byte header then a payload (two I/O calls) and replaces thread-per-connection code with async+coroutines and with fibers. Reports fiber context switches roughly three orders of magnitude faster than threads (example: ~52 μs for thread switch vs much lower for fibers) and demos that both coroutine and fiber approaches work and scale.
