windows – 资源监视器中的大量备用内存

我们的服务器有16GB的内存,我注意到资源监视器中大约10GB被标记为“待机”内存.

似乎资源监视器上的“待机”仍被视为“可用”,因此它可能不是问题.

它只是在另一个应用程序需要内存时可能会释放的缓存数据.

这是Investigate memory usage with Windows 7 Resource Monitor的好描述：

Standby

The Standby list,which is shown in blue,contains pages that have
been removed from process working sets but are still linked to their
respective working sets. As such,Standby list is essentially a cache.
However,memory pages in the Standby list are prioritized in a range
of 0-7,with 7 being the highest. Essentially,a page related to a
high-priority process will receive a high-priority level in the
Standby list.

For example,processes that are Shareable will be a high priority and
pages associated with these Shareable processes will have the highest
priority in the Standby list.

Now,if a process needs a page that is associated with the process and that page is Now in the Standby list,the memory manager immediately returns the page to that process’ working set. However,all pages on the Standby list are available for memory allocation requests from any process. When a process requests additional memory and there is not enough memory in the Free list,the memory manager checks the page’s priority and will take a page with a low priority from the Standby list,initialize it,and allocate it to that process.
