...使用頻率，我會(huì)把使用最少的緩存替換出緩存區(qū)。 Least Recently Used (LRU) 我會(huì)把最近最少使用的緩存數(shù)據(jù)踢走。 瀏覽器就是使用了我（LRU）作為緩存算法。新的對(duì)象會(huì)被放在緩存的頂部，當(dāng)緩存達(dá)到了容量極限，我會(huì)把底部的對(duì)...
LRU Discards the least recently used items first. This algorithm requires keeping track of what was used when, which is expensive if one wants to make sure the algorithm always discards the least rece...
