An LLM inference server is handling numerous concurrent requests with highly variable sequence lengths. Over time, the server's performance degrades. System monitoring reveals that while there is significant total free memory, the server struggles to allocate space for new requests' KV caches. Which statement best explains why an attention mechanism using a paged memory allocation would be more effective in this scenario compared to one using a standard, contiguous allocation?
