• Github每日精选（第15期）：Go 的快速 HTTP 包 fasthttp

    fasthttp

    fasthttp 的github地址在这里。

    在这里插入图片描述
    fasthttp 是为一些高性能边缘案例设计的。比 net/http 快 10 倍，除非您的服务器/客户端需要每秒处理数千个中小型请求并且需要一致的低毫秒响应时间，否则 fasthttp 可能不适合您。对于大多数情况net/http来说要好得多，因为它更易于使用并且可以处理更多情况。在大多数情况下，您甚至不会注意到性能差异。

    HTTP 服务器与net/http的性能对比

    简而言之，fasthttp 服务器比 net/http 快 10 倍。以下是基准测试结果。
