Zanimiva lastnost porabe sistemskega RAMa

enkrat sem tudi jaz opazil podobno, le da nisem tega meril tako kot ti.
in ko se malce brskal po netu, sem naletel na eno stran, kjer je malce bolj opisalo to porabo in res celostransko okno porabi več sredstev.

Some background on virtual memory
Windows XP uses virtual memory to simulate more RAM than physically exists in your system. When you launch an application, Windows XP loads that application into RAM. If you load several applications at the same time, all the running applications must share the same RAM. However, as you can imagine, running all those applications together will require more RAM than is actually in your system.

In order to manage this situation, Windows XP monitors each application’s use of the available RAM and locates sections of memory that are allocated to an application but aren’t currently being used. Windows XP then moves, or swaps, these inactive sections from RAM and temporarily stores them on the hard drive in a file called the paging file.

When those sections of memory are needed by their applications, Windows XP retrieves them from the paging file and places them back in RAM. Of course, to do this, Windows XP will most likely need to move other memory sections of other applications from RAM to the paging file. As you can imagine, this swapping process is continuous when you use several applications at the same time, and it can be a big drag on overall system performance.
It’s important to note that Windows XP uses a new virtual memory scheme in which it divides the physical RAM in your system in two sections—page pooled and nonpage pooled. In this scheme, the nonpage-pooled section contains crucial operating system and application files and is never sent to the paging file. Of course, anything in the page-pooled section can be swapped out to the paging file as needed.
