How you measure is as important as what you measure when it comes to improving the performance of your websites and embeddable content. Follow a real world use case using Real User Measurements across multiple delivery networks and how comparing metrics against content your do not control can help give insight on what to improve upon for you own delivery.
Christian Kaar (runtastic GmbH)
Our mobile apps have been downloaded more than 12 million times. Along the way we had to cope with operational and performance challenges. We will share three which caused us most headaches: Crash reports and why they don't help us to make users happy, how Facebook brought down our applications and what it means to have millions of blind spots in applications operation.

Cosimo Streppone (Opera Software ASA)
Working in Web Operations means dealing with production systems that in most cases needs to be operational 24x7x365. To reach 99.999% uptime, you must fail as little as possible.

What could possibly go wrong?
Tim Morrow (Betfair)
Betfair's ground-up site rebuild brought page load times down below 3 seconds. But customers still complain that the site is slow.
