-#### Key Performance Insights
-
-1. **Exceptional Insert Performance**: Up to **48% faster** insert operations with the most dramatic improvements on large datasets (10,000 items)
-2. **Consistent Get Operations**: **25-36% faster** across most cache sizes, with excellent scaling characteristics
-3. **SIMD Filter Benefits**: **3-6% improvements** in list operations with vectorized pattern matching
-4. **Memory Efficiency**: String pooling and memory layout optimizations provide measurable gains
-5. **Scalable Architecture**: Performance improvements are most pronounced with larger datasets
-6. **Sub-100ns Operations**: Most core operations (get, contains_key, insert) complete in under 100 nanoseconds
