Betfair recently launched a beta version of their Sports betting website and is in the process of rolling out the site to new customers. We would like to present our journey so far and our results:
Faster page load times Improving our operational insight into the performance of our website Significantly increasing our rate of deployment through continuous delivery How it impacted our bottom line
Our talk will explore the initiative in great detail. We will discuss:

The complexity of website content (as measured by the HTTP Archive) continues to increase. Meanwhile, the number of mobile browsing devices is increasing at more than 25% each year. Due to their limited processing power, memory, storage and network bandwidth these devices pose new challenges in terms of web performance as sites become more complex. To date, the approach to solve these issues has been to create mobile versions of web sites with limited content and simplified layout. This talk will present a new way we are looking at the mobile browsing challenges at Amazon.com. We will present data about site latency among various classes of devices and usage of mobile versions of the site. Much of the presentation will focus on technical approaches to dramatically reduce web site latency for this class of users.
How do you measure web page performance?
We all talk a lot about how fast our web pages are but are we comparing apples with apples?
There are at least 6 different ways to measure web page performance, and multiple metrics to gather such as initial render, “above the fold” time or onLoad event time.
The goal of this talk is to put web performance measurement in perspective by identifying and classifying the different ways of measuring web performance.
So what dimensions can we compare them on?
2. What metrics do they collect?
3. “Completeness” of measurement – e.g. can they measure 3rd party or CDN content?
4. Ease of implementation / use?
5. Scalability (e.g. are they suitable for “real-user monitoring” type solutions or are they more developer/single-user oriented?)
6. Are they suitable for Mobile devices?
7. Are they suitable for measuring web API’s?
8. What’s the cost?
9. Suitable for SME vs Enterprise?
We will also talk about the “active monitoring versus real-user monitoring” debate… what are the pro’s & con’s of each approach and will one eventually supplant the other?
1. Reading/writing to the DOM
2. Function calls
3. Lookups (scope lookups, property lookups, array item lookups)

Page Speed Analysis tools provide performance metrics for web-sites, and mod_pagespeed and Page Speed Service automatically rewrite web sites by applying web performance “best practices”. But exactly what is the impact on web site latency and usability from implementing these transformations? We’ll share what we’ve learned from running Page Speed and mod_pagespeed in the field.
What is the impact of specific web performance optimizations on metrics like page load time and time to first paint? What is the interaction between latency, page structure, and network-level decisions such as when to flush web pages so that browsers can start rendering? In this talk, we’ll present our latest findings and show developers how to apply these findings to their own web sites.
We’ll conclude with a discussion of new features being added to Page Speed analysis & rewriting tools to translate these learnings into a faster web.

Performance has always been something we at SPIL within Technology had thoughts about, but never really had full focus on. Within Development, the main focus has always been delivering features that the business requires from us; performance was never a mindset that we had during the creation of these features. As we have a global audience of 130 million unique visitors visiting our portals daily, we came to the conclusion that we needed to have more focus in the field of performance. We could get so much more out of our current users, by increasing their browsing experience not only from well connected broadband countries but also from countries that have more scattered performance.
We’ll share with you what we had to do to get Performance on the map, challenges we faced, what we’ve been able to achieve so far and the lessons we’ve learned up until this point. Performance is now fully on our radar and we still have many things we can and will improve.
Google Chrome gets faster and faster with every release. We’ll talk about the latest advances as well as what the team is working on now. Chrome’s speed is great for users, but let’s not forget about developers! Chrome now has the richest developer tools for making your site as fast as possible. Come learn about the new features that have us most excited.
Ghandi once said that there is more to life than increasing its speed. In the same vein there is more to making a browser amazing than making it perform fast. In this talk you’ll learn what Firefox has in store for users and developers alike and get a glimpse into how a browser can blur the line between apps and the web whilst allowing you to experience the web on your own terms.
By now we all have become aware that faster websites equal to more pageviews, visitors and revenue. In order to optimize web performance most of you have adopted and put to practice the “14 rules for creating high performance websites”. However important it may be, IT organizations don’t necessarily have the resources, time or money available to devote themselves to continuous fine-tuning their web performance. But there’s still the need to optimize and improve.
It’s time to look for a “steve-in-a-box” approach, automation of web performance optimization. But where to start, what is the ideal type of product or implementation for me? What will it cost or save me? In this session we will cover every aspect of performance automation and more. We will cover: - Automated vs Manual optimization - Current available automated solutions - Build a business case: How to determine what works best for your site? - Benchmark results of automated solutions, including comparison of: overall performance between vendors, by different types of sites and by supported optimization techniques (spriting, concat scripts, data: URI images, etc.) - Tips & Tricks for implementing performance automation within your organization
All test data will be shared publicly, including detailed overview of test setup.

Mobile browser performance is constrained by more than just bandwidth. You already know slow loading sites create a bad user experience. But even if you’ve resolved download speed, what happens to the user experience if a site is jumpy, choppy, or worse yet, non-responsive to basic interaction.
Yes, your site loads quickly even with low bandwidth. You’ve followed the 14 WOP tips. You’ve improved your sites performance, or so you think. Your app is loading quickly, but why is it not responding quickly?
