8. Application Lifecycle Demo

9. Performance

10. Application Performance
Startup is the chance to lose users
We invested heavily in startup time for Windows Phone 8
Facebook app reduced from 12 seconds to 4 seconds
Why?
Execution environment improvements
Compile in the cloud
Core CLR improvements
No work from developers – free (as in beer)!

11. Compile in the cloud
Moving to CoreCLR brings Native Image Generator (NGEN)
Code generation is expensive and time consuming on device
Compile in the cloud NGEN’s your code when you submit
Submit your XAP to marketplace just as you always have
Code in XAP is NGEN’d and the XAP updated with compiled code
What about my existing app?
7.1/7.8 apps are NGEN’d so Windows Phone 8 gets compiled version
Original 7.1 apps is kept for download to 7.1 devices

12. Performance is as much an art as it is a science
Users care about perceived performance not benchmarks
Key Performance Indicators
How often you use the app really impacts your feel for performance
4 seconds is still too long for the app you use all the time
Perception is impacted by context switching
Even if your app starts super fast if the user has to remember where they were it slows them down

13. Resuming applications
In 7.5 we allowed apps to be in a suspended state
This is great but…
Only get the benefit if you tap back or use the task switcher we resumed the apps
Task switcher isn’t a feature that every user will use

14. Multitasking
