DNS hijacking is an occurrence that sends fear into the hearts of man and beast. It takes a perfectly harmless (yet critical) process and turns it into a weapon for chaos and mayhem.
This tool, however, does not simply reside in the hands of people looking to maliciously redirect traffic for purposes I can’t quite fathom [...]

This afternoon, the two GrabPERF Agents at Technorati were switched back to using their local copies of caching BIND for resolving DNS entries.
Some folks at Microsoft who stopped by to look at their results on the Search Performance Index noticed that there were one or two outliers in the results from these locations. When I [...]

For a number of years, I have owned three very popular domain names: WebPerformance.org, WebCaching.org, and WebCompression.org. Last night, after many days of consideration, I stopped pointing them at their own distinct Web space and pointed them at this blog.
This is not a bad or evil thing, considering that for at least 18 months, the [...]

Budgets are shrinking. Resources are tight or shrinking. In a recent post, I discussed how ideas that I had been a proponent of for 2-3 years suddenly became extremely valuable to companies during the downturn of 2001-2003.
This downturn is a different beast. This means that you will need more than basic technical smarts to get [...]

When starting with new clients, finding the low-hanging fruit of Web performance is often the simplest thing that can be done. By recommending a few simple configuration changes, these early stage clients can often reap substantial Web performance improvement gains.
The harder problem is that it is hard for organizations to build on these early wins [...]

Steven Hodson of WinExtra posted a screenshot of his personal Wordpress stats for the last three years last night. I then posted my stats for a similar period of time, and Steven shot back with some question about traffic, and the ebbs and flows of readers.
Being the stats nut that I am, I went and [...]

David Cancel and I have had sort of a passing vague, same space and thought process, living in the same Metropolitan area kind of distant acquaintance for about the same year.
About 2-3 months ago, he wrote a pair of articles discussing the efforts he has undertaken in order to try and offload some of the [...]

The Web is a many-splendored thing, with a very split personality. One side is drive to find ways to make the most money possible, while the other is driven to implement cool technology in an effective and efficient manner (most of the time).
Andy King, in Website Optimization (O’Reilly), tries to address these two competing forces [...]

Port80 Software is reporting that in their survey of Fortune 1000 Web sites, IIS 6.0 has overtaken Apache as the Web server platform of choice. [here]
My two-cents: I respect the Port80 Software team greatly and love their maniacal devotion to ensuring that IIS users actually make use of the HTTP compression and caching that can [...]

This paper is an extension of the work done for another article that highlighted the performance benefits of retrieving uncompressed and compressed objects directly from the origin server. I wanted to add a proxy server into the stream and determine if proxy servers helped improve the performance of object downloads, and by how much.
Using the [...]
