vLLM bi-directional KV transfer cuts TTFT in agentic workloads
KV cache transfer addresses the hidden cost of agentic loops: re-prefilling the same context on every turn, which inflates latency and GPU spend as conversations grow. Teams running self-hosted agents on vLLM can replicate the setup on EC2 P5en instances with EFA. The reported gains also give a concrete comparison point for choosing between Qwen3-32B and GLM-5-FP8 when latency per turn matters.
