SBERT-base with smart batching processes 83 sentences/second on CPU and 2042 sentences/second on GPU; without smart batching it is 44 CPU and 1378 GPU.

Summary

Smart batching roughly doubles the throughput of the SBERT-base embedding model on both CPU and GPU, so the system should treat it as a low-effort, high-payoff optimization whenever batch processing is available. The measured rates also set a concrete expectation: the system should expect on the order of 80-90 sentences per second on CPU and around 2,000 per second on GPU under active batching, which anchors all downstream capacity planning and timeout settings.
