Web Performance, Part V: Baseline Your Data
In: Web Performance| Web performance concepts| WebPerformance.Org
30 Aug 2006Up to this point, the series has focused on the mundane world of calculating statistical values in order to represent your Web performance data in some meaningful way. Now we step into the more exciting (I lead a sheltered life) world of analyzing the data to make some sense from it.
When companies sign up with [...]
Web Performance, Part IV: Finding The Frequency
In: Web Performance| Web performance concepts| WebPerformance.Org
30 Aug 2006In 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 [...]
Web Performance, Part III: Moving Beyond Average
In: Web Performance| Web performance concepts| WebPerformance.Org
30 Aug 2006In the previous article in this series, I talked about the fallacy of ‘average’ performance. Now that this has been dismissed, what do I propose to replace it with. There are three aggregated values that can be used to better represent Web performance data:
Median
Geometric Mean
85th (or higher) Percentile
The links take you to articles that better [...]
Web Performance, Part II: What are you calling average?
In: Web Performance| Web performance concepts| WebPerformance.Org
30 Aug 2006For a decade, the holy grail of Web performance has been a low average performance time. Every company wants to have the lowest time, in some kind of chest-thumping, testosterone-pumped battle for supremacy.
Well, I am here to tell you that the numbers you have been using for the last decade have been lying. Well, lying [...]
Web Performance, Part I: Fundamentals
In: Web Performance| Web performance concepts| WebPerformance.Org
30 Aug 2006If you ask 15 different people what the phrase Web performance means to them, you will get 30 different answers. Like all things in this technological age, the definition is in the eye of the beholder. To the Marketing person, it is delivering content to the correct audience in a manner that converts visitors into [...]
I have been running the GrabPERF Compression and Performance study for less than a week, but I thought that I should share some of the initial results with everyone.
As you can see above, the byte transmission savings gained by some sites is pretty astounding. Google News sends a pages with a median weight of near [...]

Never Eat Alone: The Introvert’s Review
In: Uncategorized
27 Aug 2006I sat down and finally read my copy of Never Eat Alone, by Keith Ferrazzi. Well, I agonizingly got my way through 80% of the book before I threw it across the room in disgust.
What a load of crap.
There might be a message in the book somewhere. But the book is mostly about Mr. Ferrazzi’s [...]
Fisher Space Pen and Rite in the Rain: Bonus from a friendly supply sergeant
In: Notebook Lust
26 Aug 2006Alan at MREater hit the jackpot when he gave a supply sergeant a lift.
As a bonus he got a Fisher Space Pen. And of course…
It’s the perfect companion to the “Rite in the Rain†All-Weather Field Book the soldier also gave to me. Nothing like a friendly supply sergeant. The Field Book has paper “created [...]
When I regained consciousness…
26 Aug 2006The title is a play on an old Royal Canadian Air Farce skit.
I have been having an adverse reaction to a new medication, which the doctor asked me to stop taking today. This reaction involves am itchy rash slowly spreading all over my skin.
Tonight I took 1.5 teaspoons of Benadryl to see if that would [...]
