Web Performance Daybook Volume 2

From the Editor

Stoyan Stefanov

In the spirit of the true high-performance, non-blocking asynchronous delivery, you now have the Web Performance Daybook, Volume 2 published before Volume 1. I hope you'll enjoy reading the book as much as I enjoyed working on it and rubbing (virtual) shoulders with some of the brightest people in our industry.

Back in December 2009, I wanted to give an overview of the web performance optimization (WPO) discipline. I decided on a self-imposed deadline of an-article-a-day from December 1 to 24: the format of an advent calendar similar to http://www.24ways.org. As it turned out, 24 articles in a row was quite a challenge and so I was happy and grateful to accept the offers for help from a few friends from the industry: Christian Heilmann (Mozilla), Eric Goldsmith (AOL), and two posts from Ara Pehlivanian (Yahoo!).

The articles were warmly accepted by the community and then the following year, in December 2010, the calendar was already something people were looking forward to reading. The calendar also got a new home at http://calendar.perfplanet.com as a subdomain of the “Planet Performance” feed aggregator. And this time around more people were willing to help. Developers of all around our industry were willing to contribute their time, to share and spread their knowledge, announce new tools, and this way create a much better set of 24 articles than a single person could. This is what soon will become Volume 1 of the series of Daybooks.

Then came December ...
