它还可以帮助检测系统颠簸,当可用内存量很低并且不断地调入和调出页面以支持任务的处理时,可能会出现系统颠簸。
It also helps detect thrashing, which can occur when memory is extremely low and pages are constantly being paged in and out to support processing.
如果不加以处理,系统颠簸可能会导致系统停滞,因为内核过分地关注于为页面腾出空间,而不是完成任何有实际意义的工作。
Unabashed thrashing can literally cause a system to come to a standstill, as the kernel becomes too concerned with making room for pages than actually doing anything productive.

实际上,VMM中提供了一种内存负载控制算法,它可以检测系统是否出现颠簸,并尝试去解决这种情况。
VMM actually has a memory load control algorithm, which can detect if the system is thrashing and actually tries to remedy the situation.
当出现这种情况时,通常表示系统中发生了颠簸现象。
When this occurs, it usually signifies that thrashing is going on in your system.
然而,LSF算法造成任务之间的频繁切换或严重的颠簸现象,增大了系统开销,并限制了其应用。
However, LSF may frequently cause switching or serious thrashing among tasks, which augments the overhead of a system and restricts its application.
