Web Performance Tuning, 2nd Edition is about getting the best possible performance from the Web. This book hits the ground running, giving 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. In this second edition, the book has been significantly expanded with new chapters on Web site architecture, security, reliability, and their impact on performance. It also includes many new Perl scripts and many more examples andgraphs of real-world performance problems and their solutions. This book is for anyone who has waited too long for a web page to display, or watched the servers they manage slow to a crawl. It"s about making the Web more usable for everyone.
