Frame Performance Testing
Use this demo to learn how different operations affect frame rate.
Quick Start:
- Open DevTools (F12) and go to the Performance tab
- 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
- 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
