AI Gateway Latency Explained: Where 400ms is Lost

By PulseAugur Editorial · [1 sources] ·

An AI gateway can introduce significant latency, with a 400ms increase often indicating more than just an extra network hop. This delay can stem from various factors including connection setup, authentication, policy checks, and inefficient routing. To diagnose such issues, it's crucial to measure individual stages of the request lifecycle rather than relying solely on the total response time. Optimizing connection pooling, enabling HTTP keep-alive, and caching authentication data are key strategies to minimize gateway-induced latency. AI

IMPACT Optimizing AI gateways can reduce operational costs and improve user experience for AI applications by minimizing request latency.

    My AI Gateway Added 400ms to Every Request. Here's Where It Went

    <p>If your AI application suddenly becomes 300–500ms slower after adding an AI gateway, the first question should not be “Is the gateway slow?” It should be “Which part of the gateway is actually consuming the time?” An extra network hop can add latency, but a 400ms increase is u…
