 # 📖 Introduction
 
 `gnet` is an event-driven networking framework that is ultra-fast and lightweight. It is built from scratch by exploiting [epoll](https://man7.org/linux/man-pages/man7/epoll.7.html) and [kqueue](https://en.wikipedia.org/wiki/Kqueue) and it can achieve much higher performance with lower memory consumption than Go [net](https://golang.org/pkg/net/) in many specific scenarios.

 # 📖 简介
 
 `gnet` 是一个基于事件驱动的高性能和轻量级网络框架。这个框架是基于 [epoll](https://en.wikipedia.org/wiki/Epoll) 和 [kqueue](https://en.wikipedia.org/wiki/Kqueue) 从零开发的，而且相比 Go [net](https://golang.org/pkg/net/)，它能以更低的内存占用实现更高的性能。
