Developer cuts LLM concurrency latency by 60% with multi-worker ASGI

By PulseAugur Editorial · [1 sources] ·

A developer significantly improved LLM concurrency latency by implementing a multi-worker ASGI setup with FastAPI and Uvicorn, reducing degradation from 4.31x to 1.28x under load. This addressed a bottleneck where a single worker process serialized requests, causing substantial delays. Further optimization involved addressing synchronous database calls to Neon via SQLAlchemy that froze the asyncio event loop and incurred an 8-round-trip transcontinental tax, dropping authentication overhead from nearly a second to milliseconds. AI

IMPACT Improved LLM system performance through optimized infrastructure and reduced latency.
