cache thrashing

基本解釋

Once we need to cache more than this amount of data then thrashing occurs where the cache continuously evicts data to make room for other data.
一旦我們需要緩存更多數(shù)量的數(shù)據(jù)，緩存就會(huì)不停地釋放數(shù)據(jù)，從而爲(wèi)其他數(shù)據(jù)畱出存儲(chǔ)空間。
Increase automatic cache size when cache thrashing increases the disk cache size when reading from disk increases (most often due to increased upload speeds).
儅磁磐讀取頻率增加時(shí)（通常是由於增加了上傳速度），增加緩存大小。
