What happened and what to do
Published on August 21, 2026, the paper analyzes a year of production LLM traffic. It reports short-lived prefix reuse and tradeoffs between preserving KV cache locality and balancing load. According to the findings, FIFO or LRU policies can match or outperform more complex cache policies.
For a company operating LLM serving, these findings can inform tests of caching and load-balancing policies against representative traffic. A practical implementation could collect cache hit and reuse metrics, latency, and load distribution, then compare strategies to determine configurations suited to the company’s workload.
How the consultancy can help
Wendelmaques can diagnose the serving workload and operations, define evaluation metrics and scope, and implement monitoring pipelines and cache and balancing tests. The engagement can include operating the agreed solution.
