101 Essential Checklists

Illustration: Deliver First Class Web Sites

Continuing my series of posts on Web performance guidelines, today I'm reviewing one chapter of a new book -- Deliver First Class Web Sites: 101 Essential Checklists [Sitepoint] -- by Shirley Kaiser of SKDesigns, published by Sitepoint in July 2006.

Sitepoint's practical publications are well known among Web developers, and Kaiser deserves credit for devoting a full chapter to site performance alongside all the useful advice on other topics. As its title states, this book does not cover topics in great depth. Each checklist item is stated, then discussed briefly.

Continuing my series on Web performance guidelines, today I am reviewing another book -- Speed Up Your Site, by Andrew B. King, published by New Riders in 2003.

Today I'm going to look at another list of Top Ten Web Performance Tuning Tips, following up on my promise to review Web site and application performance advice.

Today's list of tuning tips was created by Patrick Killelea, the author of Web Performance Tuning, first published by O'Reilly in 1998, then revised in 2002.

Web Tuning Wisdom: 1

This post is the first in a new series on how to build Web pages, sites and applications that perform well -- by design. I will be combining my own observations with online research and recommendations on best practices contributed by my colleague Ben Rushlo. Ben makes his living measuring Web site performance and giving companies advice on how to improve the performance of their sites and applications.

Despite the crucial contribution of performance to online application effectiveness, good advice on the subject is surprisingly scarce on the Web, and even scarcer in books about Web design ...
