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:

  • Why we launched our Customer Commitment
  • The Betfair site architecture
  • Performance techniques applied including reducing the number of HTTP requests, reducing DNS lookups, minification, flushing the buffer early, eliminating iframes, using cookie-free domains for components, optimising CSS sprites
  • How we measure performance
  • How we measure the key business metrics including page load times, conversion rates such as registration, bets placed and revenue per customer
