# AllocationStrategy Performance `allocation_strategy_bench` evaluates the allocation-routing overhead and behavior of `RandomAllocationStrategy` and `FreeRatioFirstAllocationStrategy` across multiple Mooncake Store segments. ## Execution ```bash ./mooncake-store/benchmarks/allocation_strategy_bench --workload=dsa ``` ## Workload The benchmark compares two workload types: - **KV-only**: a general single-object-size allocation workload without indexer objects. This is used as the non-DSA baseline. - **Paired KV+Indexer**: a DSA-style workload where KV cache objects and indexer objects are allocated together. - KV cache object size: 3,274,752 B (3.12 MB) - Indexer object size: 658,432 B (643 KB) - Each round samples `N` uniformly from `[1, 128]`. - In KV-only mode, each round issues `N` KV allocations. - In paired KV+Indexer mode, each round issues `N` KV allocations followed by `N` indexer allocations. - Segment capacity: 1 TB per segment by default. - Segment counts: 1, 2, 4, 8, 16. - Replica counts: 1, 2, 3 when enough segments are available. - On allocation failure, the benchmark randomly evicts 5% of all live objects and retries. - `UtilRatio_*` is sampled only when eviction is triggered, immediately before evicting objects. `skewed=no` uses uniform segment capacity. `skewed=yes` alternates segment capacity between 1.5x and 0.5x the base capacity. ## Summary For KV-only, utilization reaches about 96.1%. For the DSA paired KV+indexer workload, both strategies reach about 95.2% utilization. The difference mainly comes from mixed object sizes in the paired workload. `RandomAllocationStrategy` generally has higher throughput and lower latency, while `FreeRatioFirstAllocationStrategy` tends to keep segment utilization more balanced. ## Result KV-only is the non-DSA baseline. It represents the common case where Mooncake Store allocates only one object size. ### KV-only / Skewed=no / Random | Replica | Segments | AllocSize | Cluster(GB) | UtilRatio_min | UtilRatio_p99 |
