Introduction to the Series
This is the first of a four-part series focusing on the reasons why companies measure their Web performance. This perspective is substantially different than ones posited by others in the field as they focus on the meat and potatoes reasons, rather than the sometimes more difficult to imagine future effects that measurement [...]

The GrabPERF Black Friday Dashboard is done for another year and there were two performance victims that suffered the most at the hands of the onslaught of bargain-hunters in the area of Web performance.
Some caveats that I need to mention about the GrabPERF measurement methodology.

Only the base HTML file of each site is measured.
Only the [...]

I fired up the Boston FIoS measurement location today after a couple of days off, and found that suddenly FIoS doesn’t like the BitTorrent.

The line of purple dots all indicate measurements that reported an error code. All of those measurements come from Boston FiOS. See the real-time graph here.
Accident? Design? That I cannot comment on. [...]

Today’s Web interfaces are all about the Flash (literally). Smooth charting, cool effects, callouts to references — ways to try and simplify complex data collections.
Problem-solving and diagnosis requires a far deeper dive than the flashiest interface could ever provide, because it comes down to the numbers. The actual measurements that make up the flashy chart. [...]

When I meet with clients, I am always astounded by the strength of the silos that exist inside companies. Business, Marketing, IT, Server ops, Development, Network ops, Finance. In the same house, sniping and plotting to ensure that their team has the most power.
Or so it seems to the outsider.
Organizations are all fighting over the [...]

Yesterday in the Fast Company Live Fail Whale session [mention on Scoble's blog here], Paul Bucheit of FriendFeed jokingly said that his company’s external alerting mechanism was Louis Gray.
I cringed when I read that, as the last people who should be letting you know you have an issue are your visitors or customers. I know [...]

The Dog and The Toolbox
One day, a dog stumbled upon a toolbox left on the floor. There was a note on it, left by his master, which he couldn’t read. He was only a dog, after all.
He sniffed it. It wasn’t food. It wasn’t a new chew toy. So, being a good dog, he walked [...]

Give almost any human being a hammer, and they will know what to do with it. Modern city dwellers, ancient jungle tribes, and most primates would all look at a hammer and understand instinctively what it does. They would know it is a tool to hit other things with. They may not grasp some of [...]

One of the ongoing themes is the way that slow or degrading response times can have a negative effect on how a brand is perceived. This is especially true when you start placing third-party content on your site. Jake Swearingen, in an article at VetureBeat, discusses the buzz currently running through the advertising world that [...]
