a system cache question

[peereli]

Hi Shane
In about cleanmem, paragraph 5 you say : The memory is pushed to the system cache, not the page file
Question: What is the physical location of this pushed memory?
Thanks

"Standby List
The Standby list contains unmodified pages that have been removed from process working sets, which effectively makes the Standby list a cache. If a process needs a page that is on the Standby list, the memory manager immediately returns the page to its working set.
All pages on the Standby list are available for memory allocation requests. If a process requests memory, the memory manager can take a page from the Standby list, initialize it, and allocate it to the calling process. This is called repurposing a page.
Pages on the Standby list are often from recently used files. By keeping these pages on the Standby list, the memory manager reduces the need to read information from the disk. Disk reads can decrease system responsiveness."

The standby list is in memory itself and not the hard drive.

Thank you for your reply Shane
There is something I must be missing, you are saying that it is in the memory itself, but wasn't it taken/cleaned from there to begin with?

The cache is in memory, but is no longer marked as in use, and after a short time will be totally freed.
