Stop Measuring Agent Infrastructure by Gateway Latency Alone

Short summary

LLM gateway benchmarks focus on single-request latency, but production agents make 5–15 calls per decision, compounding gateway overhead into workflow noise. Production systems require both a fast data plane for request routing and a reliable control plane for session persistence, cost attribution, multi-tenancy, and observability. Evaluate infrastructure on control-plane capabilities—session persistence, cost governance, and observability—not just gateway latency.

• •Agents make multiple LLM calls per decision, so single-request latency benchmarks miss the actual bottleneck
• •Production needs both a fast data plane (routing) and reliable control plane (sessions, cost governance, multi-tenancy)
