During the first practical section of this tutorial we will look at the main techniques and tools available today, using real mobile devices on stage, covering:

  • Remote inspector tools
  • Traffic analyzers and bandwidth simulators
  • Profiling tools
  • When (not) to use emulators and simulators
  • Tracking with the Web Navigation Timing API

Finally, we will see examples of techniques that are harming performance on the mobile web, and tips to achieve extreme web performance, including the use of HTTP/2, how to use high performant webviews, and the latest techniques to work with the illusion of performance.

You will be able to test live, on your own mobile device, the most common performance issues on mobile websites, webapps, and hybrid apps.

After this tutorial you will see the full picture of mobile engines today, how to measure performance on them, and best practices to deliver the fastest experience on mobile browsers and webapp platforms.

@Markus; your phone will work for most of the workshop so don’t worry. The Ubuntu Browser is based on Chromium so most of the stuff will be similar to Chrome on Android in terms of performance. See you there!

So any phone in my case will be a BQ Ubuntu Touch phone, as this is my current phone. Please advise if a different OS is better, for this tutorial, then I can bring a tablet if needed.

Hi Peter Paul, Any phone will work for the workshop. You will be able to test and try live the issues and solutions. If you are on iOS, try to update it to iOS 9. See you next week!
