Improve TTFT for Multi-Turn Agentic Workloads with Bi-Directional KV Transfer in vLLM
Bi-directional KV transfer lets prefill reuse context retained by decode, avoiding repeated prefill computation as agent conversations grow.
Why it matters: For long multi-turn workloads, avoiding repeated prefill computation can reduce TTFT and accelerator work. The benchmark deliberately disabled prefill prefix caching to emulate cache misses, so its gains should not be assumed when local prefix hits are available.
