Reflow in a web browser refers to the process of calculating the positions and geometry of elements in the document for purpose of rendering, or re-rendering its visual presentation. Every browser has its own logic for doing, and sometimes not doing, these calculations.

This talk will present some findings from testing reflow times in a variety of browsers under different conditions. I will discuss the method used to gather the data, explore cross-browser reflow differences, and give developers advice on what to avoid when doing dynamic updates to their pages to avoid costly reflows in the browser.

This is a rather intriguing topic to me. Just stumbled upon this (www.mozilla.org/newlayout/d...). Is there any prerequisite reading to your talk, Lindsey?
