Coroutine switch functions simply changing the execution stack does not involve the user and kernel mode transition, also relates to context switching, far less than the cost of the process / thread switch. Although the concept of coroutines had been made, as in recent years a growing number of languages ​​(go, Haskell) Built-in support for coroutines was only known to the developers, greatly optimizing the developers programming experience coroutine, in sync order to quickly provide programming style program logic further has multiplexed asynchronous programming IO performance.
