LLM Gateway Latency Overheads Are Negligible, Developer Finds

By PulseAugur Editorial · [1 sources] ·

A developer spent a month meticulously benchmarking LLM gateway latency, only to discover that the gateway's contribution to overall request time was negligible, often less than 1%. The actual performance bottlenecks lie in model selection, intelligent routing, caching, and prompt optimization, with model choice having the most significant impact. The author argues that focusing on microsecond-level gateway overhead is misplaced when the LLM inference itself takes orders of magnitude longer. AI

IMPACT Focusing on model selection, routing, and prompt optimization offers greater latency improvements than micro-optimizing LLM gateways.

    We Obsessed Over Gateway Latency for a Month. Then We Looked at the Actual Numbers.

    <p>I spent a month benchmarking LLM gateway overhead. Measured proxy latency down to the microsecond. Ran load tests at 500, 1000, 5000 RPS. Built dashboards to track P99 gateway overhead.</p> <p>Then my teammate asked: "What percentage of total request time is the gateway?"</p> …
