# 協程內存開銷
新版本`4.0`使用了`C`棧+`PHP`棧的協程實現方案。`Server`程序每次請求的事件回調函數中會創建一個新協程，處理完成后協程退出。
在協程創建時需要創建一個全新的內存段作為`C`和`PHP`的棧，底層默認分配`2M(C)`虛擬內存+`8K(PHP)`內存（`PHP-7.2`或更高版本）。實際并不會分配這么內存，系統會根據在內存實際讀寫時發生缺頁中斷，再分配實際內存。
> 由于`PHP-7.1/7.0`未提供設置棧內存尺寸的接口，這些版本每個協程將申請`256K`的`PHP`內存
相比于異步回調程序，協程會增加一些內存管理的開銷。有一定性能損耗。經過壓測`QPS`依然可以達到較高的水平。
