How swoole works

swoole operates in two modes. Single-threaded mode, this mode is the traditional asynchronous non-blocking Server. It is completely consistent with programs such as Nginx and Node.js. In process mode, Swoole provides a complete process management and memory protection mechanism. Even when the business logic is very complex, it can run stably for a long time.
