Phase 6-2: Promote Front FastLane Free DeDup (default ON)
Results:
- A/B test: +5.18% on Mixed (10-run, clean env)
- Baseline: 46.68M ops/s
- Optimized: 49.10M ops/s
- Improvement: +2.42M ops/s (+5.18%)
Strategy:
- Eliminate duplicate header validation in front_fastlane_try_free()
- Direct call to free_tiny_fast() when dedup enabled
- Single validation path (no redundant checks)
Success factors:
1. Complete duplicate elimination (free path optimization)
2. Free path importance (50% of Mixed workload)
3. Improved execution stability (CV: 1.00% → 0.58%)
Phase 6 cumulative:
- Phase 6-1 FastLane: +11.13%
- Phase 6-2 Free DeDup: +5.18%
- Total: ~+16-17% from baseline (multiplicative effect)
Promotion:
- Default: HAKMEM_FRONT_FASTLANE_FREE_DEDUP=1 (opt-out)
- Added to MIXED_TINYV3_C7_SAFE preset
- Added to C6_HEAVY_LEGACY_POOLV1 preset
- Rollback: HAKMEM_FRONT_FASTLANE_FREE_DEDUP=0
Files modified:
- core/box/front_fastlane_env_box.h: default 0 → 1
- core/bench_profile.h: added to presets
- CURRENT_TASK.md: Phase 6-2 GO result
Health check: PASSED (all profiles)
