Every so often, you wake up and realize that the world has changed around you. Or, to say it better, your view of the world has changed so profoundly, but also so subtly and slowly that it is imperceptible unless you take the time to look back at where you came from.
Six years ago, if [...]

It’s a rare Web site these days that hosts all of its own content. From the smallest blog to the largest retailer, Web sites farm out their images, streams, and pages to CDNs, and absorb feeds, ads, and data streams from any number of outside providers.
Effective Web performance demands that a site take responsibility for [...]

A quote from Avinash Kaushik (Occam’s Razor and @avinashkaushik) to start this post.
I have a 10/90 rule . If your budget is $100 then spend $10 on tools and professional services to implement them, and spend $90 on hiring people to analyze data you collect on your website.
The web is quite complex, you are going [...]

The moment a Web site goes live, the publishers lose control of the performance.
When I say lose control of the performance, I mean that despite everything that has been done to ensure scalability and capacity, the Web is inherently an infrastructure that is out of anyone’s direct ability to manage.
This is something that needs to [...]

Content Delivery Networks (CDNs) are a key component to any Web performance strategy. If you examine the content from any large online business or media provider, it won’t take long to find the objects that these organizations have entrusted to CDNs to ensure faster delivery and a better user experience.
When working with CDNs, it is [...]

I have had advertising on my blog for as long as I can remember. Except for the period of time when I hosted the site at Wordpress.com, I have always had AdSense, Chitika, or some other ad services content being contextually presented to my visitors.
Frankly, I found having ads up on my site extremely hypocritical, [...]

A decade of working in the Web performance industry can leave one with the idea that no matter how good a site is, there is always the opportunity to be better, be faster. However, I am beginning to believe, just from my personal experience on the Internet, that speed has reached its peak with the [...]

Once again it is time to analyze browser usage in the US for the last month. July saw the appearance of Firefox 3.5, which has replicated the pattern seen with Internet Explorer 8, where it supplants the previous version slowly and linearly as people get around to upgrading.
Can MSIE 8 overtake MSIE 7 in August? [...]

June is one of my favorite months. The sun returns (although in the Boston area there are concerned that it has been replaced by clouds and humidity), the kids get out of school (and get sent to camp), and the outdoor pool opens (and I actually swim in it).
In the US browser market, Internet Explorer [...]

This week marks a momentous time in the history of the Internet. In the United States, StatCounter reports that for the first three days of the work week (Monday – Friday), Internet Explorer 8 usage is equal to Internet Explorer 6 usage.

Tie this to the trend of decreasing Internet Explorer usage noted late last week [...]
