摘要
一种特别麻烦的现象，即抖动，可能会严重干扰分页内存系统的性能，将计算巨头(multitics、IBM System 360以及其他不一定例外的系统)降低为计算侏儒。术语“震荡”表示由于过多的分页导致的过度开销和严重的性能下降或崩溃。抖动不可避免地将内存空间的短缺转化为处理器时间的过剩。
A particularly troublesome phenomenon, thrashing, may seriously interfere with the performance of paged memory systems, reducing computing giants (Multics, IBM System 360, and others not necessarily excepted) to computing dwarfs. The term thrashing denotes excessive overhead and severe performance degradation or collapse caused by too much paging. Thrashing inevitably turns a shortage of memory space into a surplus of processor time.
