disk thrashing

基本解釋

It spent most of its time waiting for the swap disk, thrashing like Emacs on a VAX.
大多數(shù)時(shí)間都花在等待交換磁磐上，就像 VAX 上的 Emacs 一樣。
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。

In contrast, when ext3 (in "data=ordered" mode, the default) flushes data to the drive, it can result in a lot of additional seeks and, depending on the IO load, even some unnecessary disk thrashing.
相反，在 ext3（“data=ordered”缺省方式）下，將數(shù)據(jù)清倉(cāng)到磁磐時(shí)，將導(dǎo)致許多額外尋道，甚至還會(huì)引起某種不必要的磁磐抖動(dòng)（thrashing）（取決於 IO 負(fù)載）。
