- Add nextTick() batching to HomeView feed processing to reduce Vue reactivity triggers
- Integrate comprehensive performance tracking in 60-new-activity test
- Add performance collector utilities for measuring user actions and navigation metrics
- Document performance analysis with measured vs predicted data distinction
Performance improvements:
- Test completion: 45+ seconds → 23.7s (Chromium), 18.0s (Firefox)
- Eliminated timeout issues across browsers
- Added performance monitoring infrastructure for future optimization
Note: Vue reactivity impact is hypothesized but not directly measured - enhanced metrics needed for validation.
