摘要

本文分析了web服务器在模拟广域网条件下的性能。工作负载模拟了许多关键的网络特性，例如网络延迟、客户端连接的带宽限制以及拨号客户端的较小MTU大小。本研究的一个新颖方面是在网络协议栈和设备驱动程序上检查web服务器的内部行为。我们发现，与基于局域网的模拟相比，广域网的特性可能会显著改变web服务器的行为，并且可能使服务器设计的许多优化在这种环境中变得无关紧要。特别是，我们发现拨号或无线用户连接的较小MTU大小会使处理开销增加数倍。

Web server performance in a WAN environment

This paper analyzes web server performance under simulated WAN conditions. The workload simulates many critical network characteristics, such as network delay, bandwidth limit for client connections, and small MTU sizes to dial-up clients. A novel aspect of this study is the examination of the internal behavior of the web server at the network protocol stack and the device driver. We discovered that WAN network characteristics may significantly change the behavior of the web server compared to LAN-based simulations and may make many of optimizations of server design irrelevant in this environment. Particularly, we found that the small MTU size of the dial-up or wireless user connections can increase the processing overhead several times.
