Load testing embedding endpoints requires batch size analysis, not just RPS

By PulseAugur Editorial · [1 sources] ·

This article discusses the nuances of load testing embedding endpoints, highlighting that requests per second (RPS) is an insufficient metric. It explains that batch size significantly impacts throughput and latency, as fixed per-request overhead is amortized over more items. The author advises testing various batch sizes to find an optimal point where latency is minimized before it increases due to large payload sizes, and suggests using tools like Locust to simulate these varied batch requests.

    Load Testing an Embeddings Endpoint Under Batch Requests

    <p>Requests per second is the wrong unit. One embeddings request can carry one string or a thousand, and a service that sustains 50 requests per second at a batch size of one may be doing a twentieth of the work of the same service at 5 requests per second with batches of 200.</p…
