In 2004-2005, as a lark, I created my own Web performance measurement system, using PERL, PHP and MySQL. In August 2005, I managed to figure out how to include remote agents.
I dubbed it…GrabPERF. An odd name, but an amalgamation of “Grab” and “Performance” that made sense to my mind at the time. I also never [...]

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.

The last two days of using Chrome have had me thinking about the purpose of the Web browser in today’s world.

mon.itor.us, a service which also provides free Web performance measurement services, appears to be having a wee problem.

The most recent GrabPERF data on this site is available here. The issue may be corrected by the time you look at the data.
I don’t wish suffering like this on anyone. GrabPERF had it’s own 3-4 day outage [...]

It has been at least a year since I last updated everyone on the state of GrabPERF. That’s because for most of the last year, the system has been rolling along without a hitch or a major systemic change. The last major change to the agent code was alomost exactly a year ago, when I [...]

If you use GrabPERF on a regular basis, the somewhat flaky navigation method has become second nature to you. In fact, to circumvent some of the idiosyncrasies, you have probably bookmarked your favourite pages.
Yesterday, I broke your links.
