+**Strengths:** +- Open addressing with flat storage (good cache locality) +- Linear probing variant +- Low memory overhead +- SIMD optimizations for probe sequence +- Mature, battle-tested library + +**Weaknesses:** +- Can suffer from clustering under certain hash distributions +- Delete operations can degrade performance over time +- Not as cache-friendly as some newer designs + +### ankerl::unordered_dense::map + +**Strengths:** +- **Robin Hood backward shift deletion** - maintains good performance after deletes +- **Extremely cache-friendly**: separate index + data storage + - Small index array (1 byte per bucket) + - Dense data vector (contiguous storage) +- **Fast iteration** - data is contiguous, not scattered +- **Lower memory overhead** - typically 30-50% less than std::unordered_map +- **Better worst-case**: bounded probe sequence length +- **Modern C++17 design** with excellent performance characteristics + +**Weaknesses:** +- Slightly more complex deletion

Regressions** (⬇️): +- ⬇️ **Single insert/lookup**: 0-10% slower in some cases + - Two-level lookup (index → data) vs. direct + - Impact: Low (typically offset by iteration gains) + +**Overall Expected Impact**: +- 🎯 **3-12% speedup** in mapping throughput +- 🎯 **15-30% reduction** in memory footprint for mapping cache +- 🎯 **Better scalability** with varying hit counts + +## Implementation
