Performance metrics: Resurrect those we have on mobiles

[manuroe]

We used to send some metrics to GA. We should recover and send them to matomo. They would be very useful to track performance improvements that are coming.

These metrics were:

• startup (durations related to the application startup):
  • initialSync (Duration of the initial /sync request)
  • incrementalSync (Duration of the first /sync when resuming the app)
  • storePreload (Time to preload data in the MXStore implementation)
  • mountData (Time to mount all objects to be ready to start (it includes the storePreload time))
  • launchScreen (Display duration of the app launch screen)
• stats (Overall stats category):
  • rooms (The number of rooms the user is in)

Matomo renders these values like this:
