**Key Finding:** SpacetimeDB achieves **~14x higher throughput** than the next best option (SQLite RPC) and maintains nearly identical performance under high contention (only ~4% drop), while traditional databases suffer significant degradation (CockroachDB drops 96%).

**Key Finding:** SpacetimeDB reaches hundreds of thousands of TPS for the transfer workload, while the best non-SpacetimeDB result shown here is SQLite RPC at 3,236 TPS. Traditional databases also suffer significant degradation under high contention (CockroachDB drops 96%).
