Analysis of Batch Processing Trade-offs
An LLM inference system is configured to process requests in batches. The system's primary goal is to ensure that once a request begins generating text, it completes as quickly as possible. However, this configuration results in the system's processing hardware often being idle. Explain the trade-off being made by this configuration, specifically relating the observed fast completion time for individual requests to the overall system inefficiency.

An engineer is monitoring a text generation inference server that groups incoming requests into batches. They observe that while the time-to-completion for any single request within a running batch is very fast, the server's overall throughput (requests processed per hour) is low, with significant periods of hardware idleness. What is the most likely cause of this performance profile?
