Achieving Better Image Optimization 9am CT

by Billy Hoffman, Founder and CEO of Zoompf

The vast majority of the web is images and yet lossless optimization techniques only save you 15% or so.

By applying lossy optimizations you can achieve 30-70% savings. This is a huge, untapped area since the concept of ?losing data? scares most people away.

In this talk Billy shows how to intelligently approach images and their content and discuss how, where, and which of the different lossy optimizations to use to drastically shrink file sizes while maintaining quality and user experience.

About Billy Hoffman

Billy Hoffman is the founder and CEO of Zoompf, a web performance scanning vendor.

Prior to Zoompf, Billy Hoffman was the lead researcher at web security firm SPI Dynamics and served as the research manager for Hewlett-Packard's Web Security Research Group following Hewlett-Packard's acquisition of SPI in 2007.

Billy's work in the field of web security has been featured in Wired, Make magazine, The Washington Post, Slashdot, and in various other journals and Web sites.

Billy has presented his work internationally at security conferences including RSA, Black Hat, and AJAXWorld, and is also the author of the book Ajax Security, published by Addison Wesley in December 2007.

As Billy conducted web security analysis throughout the globe, he consistently noted that the performance of most websites was suboptimal.

He also noted that this lack of optimization resulted in both poor user experiences and lost revenue for website providers.

Recognizing an opportunity to apply his extensive web development skills in this exciting new area, Billy founded Zoompf to develop technology and services specifically designed to optimize website performance.


JavaScript Performance Benchmarking 10am CT

by Mathias Bynens, Front-end Web Developer

We'll be taking a look at some common JavaScript patterns and their performance penalties, as well as some useful tips and tricks.

Also, we will be talking heavily about how to properly benchmark these things, using jsperf.com.

About Mathias Bynens

Mathias Bynens works as a freelance web developer in Belgium. He likes HTML, CSS, JavaScript and Web Page Optimization.

To help with those last two things, he created jsPerf a while ago.


Improving Request and Response Headers 11am CT

by Kyle Simpson, Mozilla Software Engineer on the Dev Tools Team

Every time your browser makes a connection to the server, headers are exchanged as part of the response so that browser and server can negotiate the terms of their communication.

Most people take these headers for granted. But it's actually really important for web performance optimization that you are aware of what's being sent, and that you take some simple steps to cut down on bloated waste.

We're going to look at the most common offenders in request and response headers, and some things you can do to take action to improve the efficiency of your browser-server communication.

Such optimizations will improve not only your initial and subsequent page load times, but also the responsiveness of your Ajax calls.

About Kyle Simpson

Kyle Simpson is a JavaScript Systems Architect from Austin, TX. He focuses on JavaScript, web performance optimization, and "middle-end" application architecture.

If something can't be done in JavaScript or web stack technology, he's probably bored by it.

He runs several open-source projects, including LABjs, HandlebarJS, and BikechainJS. Kyle works as a Software Engineer on the Development Tools team for Mozilla.


HTML5 AppCache 12pm CT

by Mark Christian, Developer on Twitter Web Client

One of the more underappreciated aspects of HTML5 is the application cache, which was originally designed to enable web apps to work offline.

As the spec evolves, however, it's becoming more and more applicable to speeding up online apps, not just enabling offline apps.

Come learn about a draft technology that has the potential to decrease your load times dramatically.

About Mark Christian

Mark Christian is a front-end software engineer from Redwood City, CA. With a focus on JavaScript and an eye on the evolution of the web, Mark is trying to speed things up, one page at a time.

Mark has a strong belief that good behaviour should be automatic, and asserts that well-understood magic has a rightful place at the heart of big projects.

He has a few side projects, notably Appcache Facts and OpenKeyval.org, but spends his days on the Web Client team at Twitter.


Web Timing Specification 2pm CT

by Zhiheng Wang, Software Engineer at Google

There are ongoing works in the W3C's Web Performance WG aiming to provide the missing pieces in measuring user performance, including the NavigationTiming spec.

In this talk, we will take a look at the motivation and design behind the NavigationTiming interface.

Then we will discuss how to use the interface to augment existing instrumentations on the client side.

As a case study, we will introduce the Site Speed report in Google Analytics and see how NavigationTiming makes such report possible.

About Zhiheng Wang

Zhiheng is currently a staff software engineer in Google. Before that, he received his Ph.D. from Univ. of Michigan and was a co-founder of Zattoo Inc.

After spending his previous life chasing bits around packet-switching networks, he realized user experience could be so much different from what it looks like behind the server.

Since then, he has been burying his head into building end-user latency measurement infrastructures.

Lately, he also serves as the editors of a couple working drafts from the W3C WebPerformance WG.

Mobile Web Page Optimization 5pm CT

by Tim Kadlec, Standards-based Front-end Web Developer

Mobile web usage is exploding at an incredible rate. At the end of 2010 there were an estimated 5.3 billion mobile subscriptions. Those users have to battle latency issues, bandwidth allocations and less powerful hardware so performance becomes doubly important. It will be the sites that can provide their users the content they need quickly and efficiently that will be rewarded with user loyalty.

In this session, we'll take a look at some of the techniques for improving performance on mobile devices as well as the specific performance challenges mobile presents. We will also look at some of the common mistakes being made right now and some of the tools you can use to identify them.

About Tim Kadlec

Tim Kadlec is web developer living and working in northern Wisconsin with a propensity for efficient, standards-based front-end development. His diverse background working with small companies to large publishers and industrial corporations has allowed him to see how these standards can be effectively utilized for businesses of all sizes.
