Betfair has completed a ground-up re-write of our Sports betting web platform. We focused on the fundamentals of resiliency and performance. We measured and improved and measured again and in the process, saw our page load times drop by a factor of 5; on average our full page load is under 3 seconds. We met our promise to our customers.
But some of our customers kept telling us our new site was slow. Many sophisticated customers have chosen to stay using our previous platform; there is a big opportunity cost while those customers have not chosen to experience the new products and features we’ve delivered on the new platform.
All our indicators say our new site is fast and our customers should be happy. We all know a faster site means more money, but we’re not getting the benefits we expect.
In this talk, hear Tim Morrow tell the story of how making Betfair’s site faster for most customers actually made it 3x slower for their biggest customers. Truly, you get what you measure.
