Mozilla developer 'Pavlov' wrote up some extensive details on memory use in Firefox 3. I highly recommend that you check it out.
I borrowed some of his data and created another view of the results. For example, here's the results from Windows Vista of a number of browsers:

Today, at SXSW, I hosted a panel discussion on the "Secrets of JavaScript Libraries." We set out to discuss the behind-the-scenes nitty-gritty code that powers the universal features of the most popular JavaScript libraries.
I think the presentation went quite well. I think we could've, easily, done a 2 hour talk with all the content that [...]

if ( document.evaluate ) {}
// Does the element have [...]

Something that's frequently befuddled is the differentiation between where JavaScript is executing and where performance hits are taking place. The difficulty is related to the fact that many aspects of a browser engine are reliant upon many others causing their performance issues to be constantly intertwined.
