RAM/commit charge question

[djs0302]

I know that commit charge is the amount of memory including the page
the file that's being used by programs and the operating system. At a
certain instant Task Manager is reporting 522,916 KB of physical ram
total. The commit charge total is reporting 73,160 KB being used.
Available physical memory is reporting 410,168 KB available.
Subtracting 410,168 from 522,916 equals 112,748. If 73,160 KB is being
used by programs and the operating system then what is the remaining
39,588 KB being used for? I should also point out that the page file
usage graph is showing 71.4 MB being used.

 

[Mak]

No, commit charge is a portion of virtual memory, it is *potential* paging
file usage.
You can't do your math operations where you involve physical and virtual
memory (even if it's just a part) in one equation - it's like subtracting
apples from oranges.
Task manager's PF usage graph is commit charge, just in MB: 73160KB / 1024 =
71.4453125MB ~ 71.4MB (can be in RAM or in paging file(s) - you can't tell)
The actual paging file usage can be monitored by using Perfmon / paging file
/ %usage / _total.
The actual (virtual) memory usage can be monitored in Perfmon / process /
virtual bytes / _total.

39,588 KB being used for? I should also point out that the page file
usage graph is showing 71.4 MB being used.

The remaining RAM would be used for disk cache etc.

Windows will, by design, always attempt to find some use, anything
whatever that is of some potential benefit rather than leaving the RAM
sitting there idly going to rot. "Available physical memory" should
in some respects be referred to as "Useless physical memory" because
it represents memory for which Windows has so far been totally unable
to find any beneficial use for.

Also note that the PF Usage figure reported by Windows Task Manager
includes a large proportion of "phantom" usage with regard to the
unused portions of memory allocation requests. Windows components,
device drivers, and application programs typically request memory
allocations that are somewhat larger than what will usually be needed
under normal circumstances. By design Windows must assign memory
address space to satisfy all of the memory allocation requests that
are issued. So what happens is that RAM locations are only allocated
to the portion of the request that is actually being used and the
unused portion is allocated to the page file. Note that this
allocation of unused memory requests to the page file does not require
any actual disk activity - all that is needed is to make entries in
the memory mapping tables maintained by the CPU.

Hope this clarifies the situation.

Good luck

systeminfo tells how much of the swap is being used.

Thanks for all the replies. They were very informative.

systeminfo tells how much of the swap is being used.

It does? Where?

Ron Martell Duncan B.C. Canada

 

[Bob I]

Actually it tells how much is available.

run it form the command prompt.

 

[Ken Blake, MVP]

Actually it tells how much is available.

Actually it tells both. It shows all three of the following:

Virtual Memory: Max Size:
Virtual Memory: Available:
Virtual Memory: In Use:

run it form the command prompt.

Run it from a command prompt *window* that you get by running CMD, not the
command prompt at the Start | Run line. If you do the latter, the results
won't stay on the screenlong enough to read.

 

[Bob I]

My bad, missed the itty bitty number!

it *tells* quite inaccurately (YMMV).
Example.
WinXP version tells this (correct numbers are in brackets):
Total Physical Memory: 2,047 MB (2,047 MB)
Available Physical Memory: 570 MB (570 MB)
Virtual Memory: Max Size: 8,034 MB (4,092 MB)
Virtual Memory: Available: 5,208 MB (4,076.3 MB)
Virtual Memory: In Use: 2,826 MB (15.7 MB. Perfmon %0.383 of 4092 MB
allocated)
Page File Location(s): C:\pagefile.sys

W2k3 version (checking the same machine as above, only wording changed):
Total Physical Memory: 2,047 MB (2,047)
Available Physical Memory: 570 MB (570 MB)
Page File: Max Size: 8,034 MB (4,092 MB)
Page File: Available: 5,208 MB (4,076.3 MB)
Page File: In Use: 2,826 MB (15.7 MB)
Page File Location(s): C:\pagefile.sys

GUI one (msinfo32) is not better.

And that is a third value for page file usage. I wonder what this one
actually represents?

From my machine at this moment:
Virtual Memory in use: 40 mb (from systeminfo in a command prompt
window)
PF Usage: 396 mb (from Task Manager)
Current pagefile usage 31 mb (from Bill James' utility)

Pick a number, any number.

Ron,
systeminfo shows the wrong info.
task manager has no way of showing page file usage (PF Usage in TM is commit
charge) - so that's out of the picture.
Looks like Bill James' WinXP-2K_Pagefile.vbs (is this the one you are
talking about?) script shows the same info as Perfmon - so that's correct.

hmm.. what ideas? why have to?
I just pointed out that systeminfo provides inaccurate information and
gave
example.. and that's all there is on the subject.

it *tells* quite inaccurately (YMMV).
Example.
WinXP version tells this (correct numbers are in brackets):
Total Physical Memory: 2,047 MB (2,047 MB)
Available Physical Memory: 570 MB (570 MB)
Virtual Memory: Max Size: 8,034 MB (4,092 MB)
Virtual Memory: Available: 5,208 MB (4,076.3 MB)
Virtual Memory: In Use: 2,826 MB (15.7 MB. Perfmon %0.383 of 4092 MB
allocated)
Page File Location(s): C:\pagefile.sys

W2k3 version (checking the same machine as above, only wording changed):
Total Physical Memory: 2,047 MB (2,047)
Available Physical Memory: 570 MB (570 MB)
Page File: Max Size: 8,034 MB (4,092 MB)
Page File: Available: 5,208 MB (4,076.3 MB)
Page File: In Use: 2,826 MB (15.7 MB)
Page File Location(s): C:\pagefile.sys

GUI one (msinfo32) is not better.

systeminfo tells how much of the swap is being used.

I know that commit charge is the amount of memory including the page
the file that's being used by programs and the operating system. At a
certain instant Task Manager is reporting 522,916 KB of physical ram
total. The commit charge total is reporting 73,160 KB being used.
Available physical memory is reporting 410,168 KB available.
Subtracting 410,168 from 522,916 equals 112,748. If 73,160 KB is being
used by programs and the operating system then what is the remaining
39,588 KB being used for? I should also point out that the page file
usage graph is showing 71.4 MB being used.

The remaining RAM would be used for disk cache etc.

Windows will, by design, always attempt to find some use, anything
whatever that is of some potential benefit rather than leaving the RAM
sitting there idly going to rot. "Available physical memory" should
in some respects be referred to as "Useless physical memory" because
it represents memory for which Windows has so far been totally unable
to find any beneficial use for.

Also note that the PF Usage figure reported by Windows Task Manager
includes a large proportion of "phantom" usage with regard to the
unused portions of memory allocation requests. Windows components,
device drivers, and application programs typically request memory
allocations that are somewhat larger than what will usually be needed
under normal circumstances. By design Windows must assign memory
address space to satisfy all of the memory allocation requests that
are issued. So what happens is that RAM locations are only allocated
to the portion of the request that is actually being used and the
unused portion is allocated to the page file. Note that this
allocation of unused memory requests to the page file does not require
any actual disk activity - all that is needed is to make entries in
the memory mapping tables maintained by the CPU.

Hope this clarifies the situation.

Good luck
