Task Manager Performance tab
[[The Performance tab displays a dynamic overview of your computer's
performance, including:
* Totals, in kilobytes, for physical, kernel and commit memory.
physical
The physical memory installed on your computer.
kernel
Memory used by the operating system. Non-paged kernel memory is available
only to the operating system. Paged memory can be used by other programs
when necessary.
commit
Memory allocated to programs and the system. Because of virtual memory, the
value listed under Commit Peak memory may exceed the maximum physical
memory.]]
From Task Manger HELP
The memory that Windows is using itself or that it has handed over to
applications is called the Commit Charge, because Windows has committed it
to use.
[[Commit Charge (K)
Memory allocated to programs and the operating system. Because of memory
copied to the paging file, called virtual memory, the value listed under
Peak may exceed the maximum physical memory. The value for Total is the same
as that depicted in the Page File Usage History graph.]]

Commit Charge: Total
Size of virtual memory in use by all processes, in kilobytes.
Commit Charge: Limit
Amount of virtual memory, in kilobytes, that can be committed to all
processes without enlarging the paging file.
Commit Charge: Peak
The maximum amount of virtual memory, in kilobytes, used in the session.
The commit peak can exceed the commit limit if virtual memory is expanded.

[[Performance fields overview
The Performance tab displays a dynamic overview of your computer's
performance. Click one of the following for more information:
CPU Usage
A graph indicating the percentage of time the processor is working. This
counter is a primary indicator of processor activity. View this graph to see
how much processing time you are using. If your computer seems to be running
slowly, this graph could display a higher percentage.
CPU Usage History
A graph showing how busy the CPU has been over time. The sampling displayed
in the graph depends on the value you select for the Update Speed on the
View menu. Updates occur with these possible values: High = twice per
second; Normal = once every two seconds; Low = once every four seconds;
Paused = display doesn't automatically update.
PF Usage
The amount of paging file being used by the system. If your computer is
running near the maximum, you can increase the page file size.
Page File Usage History
Graph depicting the amount of page file used over time. The sampling
displayed in the graph depends on the value you select for the Update Speed
on the View menu.
Totals
Totals for the number of handles, threads, and processes running on the
computer.
Commit Charge (K)
Memory allocated to programs and the operating system. Because of memory
copied to the paging file, called virtual memory, the value listed under
Peak may exceed the maximum physical memory. The value for Total is the same
as that depicted in the Page File Usage History graph.
Physical Memory (K)
The total physical memory, also called RAM, installed on your computer.
Available represents the amount of free memory that is available for use.
The System Cache shows the current physical memory used to map pages of open
files.
Kernel Memory (K)
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.]]
