High-Performance Server Architecture-Jeff Darcy

The purpose of this document is to share some ideas that I’ve developed over the years about how to develop a certain kind of application for which the term “server” is only a weak approximation. More accurately, I’ll be writing about a broad class of programs that are designed to handle very large numbers of discrete messages or requests per second. Network servers most commonly fit this definition, but not all programs that do are really servers in any sense of the word. For the sake of simplicity, though, and because “High-Performance Request-Handling Programs” is a really lousy title, we’ll just say “server” and be done with it.

这篇文档的目的在于分享一些思路，关于我多年来如何开发某些特定的应用——可以近似地称为‘’服务器‘’。更准确地说，我即将写就的是关于广义上旨在解决吞吐量（每秒处理数量巨大的非连续消息或者请求）的一类程序。网络服务器最符合这个定义，但并非所有程序所完成的功能是真正意义上的服务器程序。简而言之，因为“高性能请求处理问题”真的是一个非常蹩脚称谓，所以我们称这类程序叫做“服务器”，且一直以来就是这么叫的。
