内容説明
As long as there's been a Web, people have been trying to make it faster. The maturation of the Web has meant more users, more data, more features, and consequently longer waits on the Web. Improved performance has become a critical factor in determining the usability of the Web in general and of individual sites in particular. This text is about getting the best possible performance from the Web: streamlining Web content, getting optimal performance from a browser, tuning both client and server hardware, and maximizing the capacity of the network itself. It offers concrete advice for quick results - the "blunt instruments" for improving crippled performance right away. The book then shifts gears to give a conceptual background of the principles of computing performance. The latter half of the book examines each element of a Web transaction - from client to network to server - to find the weak links in the chain and show how to strengthen them. Topics covered include: Web site architecture, security, reliability, and their impact on performance; discussion of scalability of Java on multi-processor servers; Perl scripts for writing Web performance spiders that handle logins, cookies, SSL, and more; instructions on how to use Perl DBI and the open source program gunplot to generate performance graphs on the fly; and coverage of Rstat, a Unix-based open source utility for gathering performance statistics remotely. In addition, the book includes many more examples and graphs of real-world performance problems and their solutions, and has been updated for Java 2.

Whether you're administering a Web site, managing an intranet, or just browsing the Web, performance should be a chief concern. In
Web Performance Tuning, author Patrick Killelea tackles this challenging topic with a methodical string of problems and possible solutions. This title is most beneficial for those maintaining Web sites but offers several browser-related tips and solid technical background for users of any level.
The first part of this book discusses the basic performance challenges for both the browser and server sides of the equation and advises on an overall approach for identifying and attacking performance bottlenecks. The author offers many important questions for you to keep in mind and some useful techniques for measuring Web performance. This section wraps up with a few case studies that exhibit common problems.
The meat of the book is an in-depth look at all of the aspects of Web performance. The author begins with the client browser and operating-system software, discusses network hardware and protocols, and finally addresses the complex nature of server configurations. He finishes with a discussion of Common Gateway Interface (CGI) and Java scripts and some quick coverage of tuning Web databases.
Throughout the book, Killelea addresses popular application software titles, but with an emphasis on Unix servers. While Web Performance Tuning is a helpful tool for tweaking your Web connections, it also serves as an excellent primer on the technical details of the Web. --Stephen Plain
