Evaluating an LLM Serving Strategy for Different Use Cases
An engineering team is deploying a large language model for two distinct applications: (1) a real-time conversational chatbot where users expect consistently fast replies to short questions, and (2) an offline document analysis service where maximizing the number of long documents processed per day is the primary goal. The team is considering an inference serving strategy that maximizes hardware utilization by always prioritizing the initial, computationally heavy processing of newly arrived long documents over generating the next token for shorter requests already in progress. Evaluate the suitability of this strategy for each of the two applications. Justify your reasoning based on the performance trade-offs involved.

An engineering team is analyzing the performance of a new LLM inference server that uses a system to group incoming requests for efficient processing. They observe that the server's hardware is consistently busy, indicating high throughput. However, user feedback is negative, with many complaining that response times are extremely unpredictable; a short question might get an answer instantly one moment, but a similar short question might take many seconds the next. The server handles a mix of long document analysis requests and short conversational queries. What is the most probable explanation for this high variability in response time for short queries?
