Key Changes:
- Reduced static capacity from 16 to 12 SuperSlabs per class
- Fixed prefill threshold from hardcoded 4 to match capacity (12)
- Updated environment variable clamping to [1,12]
- This allows warm pool to actually utilize its full capacity
Performance:
- Baseline (post-unified-cache-opt): 4.76M ops/s
- After Phase 1: 4.84M ops/s
- Improvement: +1.6% (expected +15-20%)
Note: Actual improvement lower than expected because the warm pool
bottleneck is only part of the overall allocation path. Unified cache
optimization (+14.9%) already addressed much of the registry scan overhead.
