This benchmark can be used even without DDN EXAScaler—local disks are sufficient—and it should also allow for fair comparisons with services like InfiniStore. |

Hello maintainers, long time no see!
We’ve added a new demo using the CxS benchmark to demonstrate the effectiveness of KV tiering. By leveraging DDN EXAScaler, we show that the number of sessions that can be sustained with TTFT < 2s increases.
Of course, vLLM’s prefix caching and chunked prefill are both enabled, and LMCache’s host memory cache is also enabled. Even with all of these optimizations, this benchmark highlights the added value of integrating storage—one of the key strengths of the CxS benchmark.
