PF Usage

[shawshank62]

In task manager, what is the deal with Page File usage? Is it better to be low or high? how is 172mb? Never really thought about it before till i was looking at it today and began to wonder what it was.

This is what I know about it.
PF Usage is the amount of paging file being used by the system. This includes RAM and Virtual memory (Swap File).

Physical Memory is is just that, the amount of RAM in your system. If the difference between total and available is what is shown under PF Usage then you are not using the swap file at that time.

Commit Charge Total is the same as what is being shown under PF Usage. Commit Charge Limit is the sum of your RAM and Swap File.

Kernel Memory is memory used by the operating system kernel and device drivers. Paged is memory that can be copied to the paging file, thereby freeing the physical memory. The physical memory can then be used by the operating system. Nonpaged is memory that remains resident in physical memory and will not be copied out to the paging file.
