Which profiling approach is best for analyzing frame rate issues?
Performance recording with frame data is best because: 1) Shows frame-by-frame rendering performance, 2) Identifies frame drops and jank, 3) Visualizes main thread activity impact on frames, 4) Shows GPU activity and compositing, 5) Helps identify long frames and their causes, 6) Provides FPS metrics over time, 7) Shows relationship between JavaScript and rendering, 8) Essential for smooth animation optimization.
