Frame Performance Testing

Use this demo to learn how different operations affect frame rate.

Quick Start:

  1. Open DevTools (F12) and go to the Performance tab
  2. Click Record and try these operations:
    • Change the animation speed
    • Start the stress test (Use the CPU throttling option so every execution takes more than 50 ms)
    • Enable the heavy animation
  3. Stop recording and analyze the results:
    • Check the flame graph for long tasks
    • Identify any dropped frames
    • Use the "Screenshots" view to see how the UI was affected during the recording
    • Use the "Call Tree" view to see how much time was spent in each function
    • Analyze the impact of different animation speeds on performance
