This week, I have been discussing the different approaches to blog analytics that can be used to determine what posts from a blog’s archive are most popular, and whether a blog is front-loaded or long-tailed. The thesis is that it’s not always what the words in the blog are that are important.
In a guest post [...]

Since I started self-hosting this blog again on August 6 2008, I have been trying to find more ways to pull traffic toward the content that I put up. Like all bloggers, I feel that I have important things to say (at least in the area of Web performance), and ideas that should be read [...]

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 [...]

While this post is aimed at Web performance, the curse of the single metric affects our everyday lives in ways that we have become oblivious to.
When you listen to a business report, the stock market indices are an aggregated metric used to represent the performance of a set group of stocks.
When you read about economic indicators, [...]

When I re-introduced my five articles on Web Performance Concepts last night, I had forgotten than I had already written two additional articles in the series.

Web Performance, Part VI: Benchmarking Your Site
Web Performance, Part VII: Reliability and Consistency

Look for Parts VII and IX in the next few days.

Two years ago I created a series of five blog articles, aimed at both business and technical readers, with the goal of explaining the basic statistical concepts and methods I use when analyzing Web performance data in my role as a Web performance consultant.
Most of these ideas were core to my thinking when I developed [...]

My system has a daily job to collect and aggregate the IP Blocks distributed by the five registrars into a single database, and then provide high-level WHOIS information for this data. If you want to try this yourself, the interface here.
On an extremely irregular basis, I aggregate the statistics from this data, and present it [...]

In the last article, I discussed the aggregated statistics used most frequently to describe a population of performance data.

The pros and cons of each of these aggregated values has been examined, but now we come to the largest single flaw: these values attempt to assign a single value to describe an entire population of numbers.
The [...]

Over the last year, GrabPERF has been something that has caught the fancy of a few in the Blogging/Social Media world. It has given some perspective of how performance can affect business and image in the connected world.
But what of GrabPERF itself? It has been on a development hiatus for the last few months due [...]

This afternoon, StatCounter showed a marked increase in performance.

Normally I wouldn’t highlight an issue that only lasted an hour, but this appears to have been a very unusual issue that saw the page size decrease to nearly nothing, and performance shoot up to around 45 seconds. This combination usually indicates a back-end application timeout which [...]
