Five Articles Worth Reading About Client-Side Performance

The days of focusing on server performance appear to be shrinking. We need to build-up our skills in the area of client side processing. While I’ve made a number of posts on the subject over the past 18 months, new posts might become more of a daily or weekly pattern. There are five articles that I would like to have the team read. They are quick reads. Four out of the five should take less then 10 minutes. The PowerPoint presentation from Yahoo might take a little longer. Abstracts below:

A Study of Ajax Performance Issues

The first article comes from the blog Direct from Web2.0 . It covers 6 points that are primarily about the competitive browsers during the early part of 2008. Nothing is captured about Google Chrome as the browser was not available at the time. It’s definitely a good primer to read.

  • Array Is Slow on All Browsers
  • HTML DOM Operation Performance in General
  • Calculating Computed Box Model and Computed Style
  • FireFox Specific Performance Issues
  • IE Specific Performance Issues
  • Safari Specific Performance Issues

Optimizing Page Load Time

The second article is about Optimizing Page Load time in web applications. The author Aaron Hopkins covers a lot of the information that the YSlow team has written about over the past 2 years. The author has a very comprehensive list of tips, plus about 1/2 dozen links of comparative information on the topic of client side performance. This is definitely worth reading and following the links.

HTTP Caching and Cache Busting Presentation from Yahoo

This third article takes the prize for being the most comprehensive of the group. It’s really a presentation from the Apache Conference back in 2005 from Michael Radwin of Yahoo . For those of you who want to know more about HTTP caching, this takes the prize.

Caching Tutorial

This is a somewhat obscure article that came from Mark Nottingham. What I like about this posting is how he simplifies the topic of web caching. He doesn’t make the sophisticated reader feel bored or the unknowing reader feel stupid. He simply states the data with very clear and easy to understand content.

Circumventing Browser Connection Limits for Fun and Profit

This fifth article comes from Ryan Breen at Gomez. He’s the author of Ajax Performance. What Breen is talking about is that not all browsers behave the same. Most load in a synchronous fashion that still cause latency when interacting with a client-rich page. These browsers can be manipulated to do parallel operations, but require configuration changes. The author makes a great point about why configuring these changes can really speed up performance.
