Measure and optimize LLM response times — TTFT, TPS, P99 latency, and streaming performance.
Five passes over the same idea, each from a different angle. Do them in order, or jump to whichever you need.
LLM latency analysis tracks Time to First Token (TTFT), tokens per second (TPS), total response time, and tail latencies (P95/P99). Factors: model size, prompt length, output length, region, and load. Optimization: streaming, caching, shorter prompts, smaller models, and edge deployment.
