This example demonstrates performance measurement of dynamic imports: 1) It uses the Performance API to measure precise loading times, 2) It tracks both successful loads and failures with timing information, 3) The metrics are reported to an analytics system for monitoring, 4) This approach enables identifying slow-loading modules or problematic patterns, 5) It helps establish performance baselines and detect regressions, 6) The pattern can be extended to include more detailed metrics like parsing time, 7) This technique is valuable for understanding real-user performance in production, 8) It represents a best practice for performance-conscious applications using dynamic imports.
