-| **bdcache** | S3-FIFO | **8.61** | **0 allocs** | ✅ Auto (Local files + GCP Datastore) |
-| golang-lru | LRU | 13.02 | 0 allocs | ❌ None |

+| **bdcache** | S3-FIFO | **8.61** | Yes |
+| golang-lru | LRU | 13.02 | ❌ None |
+| otter | S3-FIFO | 14.58 | ⚠️ Manual (Save/Load entire cache) |

 > ⚠️ **Benchmark Disclaimer**: These benchmarks are highly cherrypicked to show S3-FIFO's advantages. Different cache implementations excel at different workloads - LRU may outperform S3-FIFO in some scenarios, while TinyLFU shines in others. Performance varies based on access patterns, working set size, and hardware.
