UDP vs TCP，速度快多少? [英] UDP vs TCP, how much faster is it?

问题描述

用于一般协议消息交换，可以忍受某些数据包丢失. UDP over TCP效率高多少?

For general protocol message exchange, which can tolerate some packet loss. How much more efficient is UDP over TCP?

推荐答案

UDP比TCP快，原因很简单，因为其不存在的确认数据包(ACK)允许连续的数据包流，而不是TCP确认一组数据包，这些数据包是使用TCP窗口大小和往返时间(RTT)计算的.

UDP is faster than TCP, and the simple reason is because its non-existent acknowledge packet (ACK) that permits a continuous packet stream, instead of TCP that acknowledges a set of packets, calculated by using the TCP window size and round-trip time (RTT).
