File average access time. a The average response time for four cache policies to retrieve all files. It can be seen that TQC is better than LFU and LRU, and FIFO is the worst policy. b The average access time of five file types. The average response time of FIFO for all objects is the highest. And the time cost of LFU and TQC is the smallest. However, TQC has five types whose response time is not more than 50 ms, LFU has two while LRU has none. TQC can eventually achieve a stable state for each file after a long time of learning
