吞吐量:表示没有丢包时的最大数据传输速率,单位通常为 b/s (比特 / 秒)或者 B/s(字节 / 秒),吞吐量受带宽的限制,吞吐量 / 带宽也就是该网络链路的使用率。 延时:表示从网络请求发出后,一直到收到远端响应,所需要的时间延迟,表示建立连接需要的时间(比如 TCP 握手延时),或者一个数据包往返所需时间(比如...
当套接字处于监听状态(Listening)时, • Recv-Q 表示全连接队列的长度。 • Send-Q 表示全连接队列的最大长度。 所谓全连接,是指服务器收到了客户端的 ACK,完成了 TCP 三次握手,然后就会把这个连接挪到全连接队列中。这些全连接中的套接字,还需要被 accept() 系统调用取走,服务器才可以开始真正处理客户...
