Web Performance Tuning

Web Performance Tuning shows how to get the best performance from the Web. It isn't just about tuning the web server software; it's about getting optimal performance from a browser, tuning the hardware (on both the server and browser ends), and maximizing the capacity of the network itself. Web Performance Tuning hits the ground running, giving concrete advice for quick results--the "blunt instruments" for improving crippled performance right away. It then pulls back and gives a conceptual background of the principles of computing performance, followed by a look at each element of a web transaction--from client to network to server--to examine the weak links in the chain and how to strengthen them. This book is for anyone who has waited too long for a web page to display, or watched servers slow to a crawl. It's about making the Web more usable for everyone.

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
