Deploying large language models (LLMs) in production presents unique challenges compared to development testing. While models may perform quickly in isolated tests, their performance often degrades significantly in real-world scenarios due to factors like concurrent user requests, varying prompt lengths, and GPU memory limitations. Understanding the distinct phases of LLM inference—prefill and decode—and their respective bottlenecks is crucial for optimizing performance. Techniques such as continuous batching, quantization, and speculative decoding can address specific resource constraints, but effective deployment requires careful benchmarking with realistic traffic patterns to identify and resolve the precise sources of latency.
