Subsequent Launch Latency

Summary

Measures elapsed time from a launch of an application already in memory to a series of defined startup events.

Usage

Test Cases

Launch each of the following apps from a warm state:

  • Browser
  • Calendar
  • Camera
  • Clock
  • Contacts
  • Dialer
  • Email
  • FM Radio
  • Gallery
  • Marketplace
  • Music
  • Settings
  • SMS
  • Template
  • Usage
  • Video

For each app, report the time elapsed to the following events:

  • moz-chrome-dom-loaded
  • moz-chrome-interactive
  • moz-app-visually-complete
  • moz-content-interative
  • moz-app-loaded

Development

Design

These tests use the same workload and instrumentation as the Launch Latency tests.

Common Setup

  1. Set up workload
  2. Restart B2G Process
  3. Invoke launch programmatically
  4. Close app

All Cases

  1. Invoke launch programmatically
  2. Inject the Performance Helper and save start time
  3. App instrumentation throws timeline events at appropriate times
  4. Performance helper observes events
  5. Event emit times are compared with start time for time elapsed

Results

  • Result is time elapsed to each event
  • Execute test 30 times, for each event report mean, median, deviation
