Talk at php|tek 2009 (English - US)
You have done all the caching tricks in the book on the server side: memcache, apc, database cache and so on and squeezed every millisecond out of it, now your site is as fast as it will ever get. Well guess again !
Too often people forget that what you are effectively caching and creating with those technologies is the HTML part of the user response time, now if they are done correctly then HTML is 10 - 20% of your users response time, so there is room for a whole lot of improvements on those other 80 - 90%.
You will be taken through a couple of important steps to achieve this, such as how to optimize your JavaScript, CSS, Images, Cookies and a whole sleeve of other things that make frontend caching the magical place that it is.
After having attended this talk you will not only have learned to make your sites faster for your long term users but also people coming for the first time as well as people on slower connections.

A good presentation - although I've been over the YSlow concepts/suggestions before and your presentation covered a lot of what Yahoo offers as performance suggestions.
It's probably not a bad idea to direct the audience to check out the YSlow plugin for Firefox, and the materials distributed by Yahoo.
There was that awkward question/answer moment during the presentation due to the fact that it was not clearly communicated that a browser does not saturate a given computer's total bandwidth. Perhaps more information could be given in regards to actual browser functionality, request pipe-lining, and actual bandwidth usage.
