UnverifiedIn video generation scenarios, increasing frame count causes sequence length to grow rapidly, with KV cache volume growing linearly, making it easy to exceed on-chip SRAM capacity and degrade to lower-bandwidth HBM, creating a real-time bottleneck.76% similarVerifiedThe cost of persistent KV caching is a significant increase in storage space, along with the engineering challenge of efficiently locating and loading relevant segments from a massive cache.76% similarUnverifiedTypical signals of a storage bottleneck include low database CPU utilization but persistently high query latency, noticeably elevated iowait, and continuously growing disk queue depth.75% similarUnverified主机卸载用带宽换显存空间，代价是数据传输延迟；激活重计算用算力换显存，二者可互补配合75% similarUnverifiedAs context length increases, the memory footprint of the KV Cache grows dramatically, becoming a key factor limiting concurrency.75% similar
