Phase 3 C3: Static Routing A/B Test ADOPT (+2.20% Mixed gain)
Step 2 & 3 Complete:
- A/B test (Mixed 10-run): STATIC_ROUTE=0 (38.91M) → =1 (39.77M) = +2.20% avg
- Median gain: +1.98%
- Result: ✅ GO (exceeds +1.0% threshold)
- Decision: ✅ ADOPT into MIXED_TINYV3_C7_SAFE preset
- bench_profile.h line 77: HAKMEM_TINY_STATIC_ROUTE=1 default
- Learner auto-disables static route when HAKMEM_SMALL_LEARNER_V7_ENABLED=1
Implementation Summary:
- core/box/tiny_static_route_box.{h,c}: Research box (Step 1A)
- core/front/malloc_tiny_fast.h: Route lookup integration (Step 1B, lines 249-256)
- core/bench_profile.h: Bench sync + preset adoption
Cumulative Phase 2-3 Gains:
- B3 (Routing shape): +2.89%
- B4 (Wrapper split): +1.47%
- C3 (Static routing): +2.20%
- Total: ~6.8% (35.2M → ~39.8M ops/s)
Next: Phase 3 C1 (TLS Prefetch, expected +2-4%)
