Timer Precision + +`process.hrtime.bigint()` provides nanosecond precision but: +- Minimum measurable time: ~28-30ns (after JIT warmup) +- Timer call overhead: ~30-40ns best case, ~1μs average +- Occasional spikes to milliseconds (GC/kernel scheduling) + +### 2. JIT Impact + +V8's JIT significantly affects measurements: +- Cold code: ~190ns/call for fibonacci +- Warm code: ~29ns/call (6.5x faster) +- Stabilization: ~1,000-2,000 iterations +- **Recommendation:** Always warmup before measuring + +### 3. Measurement Consistency + +Coefficient of variation across runs: 83.38% (high variance) +- Caused by JIT warmup and GC pauses +- Mitigation: Multiple runs, discard outliers, focus on relative % + +### 4. Relative vs Absolute Accuracy + +**Relative accuracy is excellent:** +- Correctly ranks operations by cost +- Identifies hot spots accurately +- Percentage-based reporting is reliable + +**Absolute accuracy is moderate:** +- Timer overhead inflates small operations +- Should not rely on absolute nanosecond values for fast lines +- Use call counts + relative % instead + +--- + +## Implementation Recommendations for Codeflash + +### Recommended Architecture + +``` +┌─────────────────────────────────────────────────────────────┐ +│ JavaScript Line Profiler │ +├─────────────────────────────────────────────────────────────┤ +│ 1.
