When you load-test LLM-backed features, exercise coordinated bursts, long-held requests, backpressure and realistic retry logic, and measure connection-pool saturation and tail latency. These features can concentrate demand and keep connections open while models compute, provoking client retries and downstream contention, so mock model delays and rate limits rather than a fast stub.
