Web performance matters. Responsive sites can make the online experience effective, even enjoyable. A slow site can be unusable. This site is about online performance, how to achieve and maintain it, its impact on user experience, and ultimately on site effectiveness.

Web Analytics Vendors Adapt to Web 2.0
Most hosted Web Analytics vendors charge you according to page views -- not unreasonable since each view is a call to their server and a new record in their database. But what happens when Ajax and other rich applications eliminate the notion of a "page"?
That's from Web 2.0 Changes Web Analytics Pricing Models, a recent post by Phil Kemelor in CMP's Intelligent Enterprise Weblog. Describing how he sees Web Analytics (WA) vendors adapting to Web 2.0, Phil continues ...

Improving Web 2.0 Application Performance
Performance Management (SLM) Challenges for Web 2.0, Ajax, and Rich Internet Applications (RIA's)
Last week, TechTarget published an article by Patrick Lightbody about the performance of Web 2.0 applications. The article's technical core -- which I review below -- is a useful checklist of ten recommendations for developing and testing Web 2.0 applications with performance in mind.
For the full article, see Ten ways to improve testing, performance of Web 2.0 applications.
Because I believe in systematic performance engineering, I am always pleased when writers advocate proactive approaches to application performance. It's the only rational way to ensure acceptable performance in production applications. So it's too bad that Patrick feels the need to justify his good advice by surrounding it with an introduction and conclusion that suffers from all the worst features of Web 2.0 coverage. A few half-truths are buried in an amalgam of excessive hype, false claims, meaningless analysis, and an optimism that underestimates the real technical challenges.

Ten Performance Testing Lessons
Using Tools Effectively
Learning how to use a tool is the easy part, it's what you do with the tool that matters.
Buying test tools is sometimes just like buying a new car: the salesman tells you that the car is reliable and has a great warranty; then the finance person warns of everything that could go wrong that isn't covered in the warranty and trys to sell you an extended warranty and maintenance contract.
Ben Simo, the author of the first paragraph, writes the blog Quality Frog. He is a software tester and test automation developer. His blog contains his "ramblings about software testing" and links to useful resources. In his post Performance Testing Lessons Learned, Ben shares his experiences with load testing and load testing tools.

Taming the Technorati Monster
Most bloggers, especially those who work in high tech, want to like Technorati. Its mission (and even its name) appeals to our vanity. When Technorati launched in November 2002, that mission was simple and easy to understand. By tracking links among blogs, and finding the most popular, it would determine which blogs were the most authoritative.
Over the years, that mission expanded from simply tracking the 100 most popular blogs to include periodic reports on the state of the blogosphere.
