Watching Virtual Memory

W

W. Watson

I see that one can use of the main menu Accessories->System Tools to see how
much of memory is used, and what the size and use is off VM. Is there
another way to monitor these sizes continually? Is it possible to change the
size of VM?

What problem are you trying to resolve?

You can use the Reliability and Performance Monitor in the Administrative
Tools.

You can change the amount of VM that a program can use. Really, though, you
only have a choice of a maximum of 2 GB or a maximum of 3 GB.
You cannot change the amount of VM that a program is using.

You can monitor your page file usage with Bill James's Page File
Monitor for Windows XP. See

size of VM?



Possible? Yes,

A good idea? Not generally.

I'll check out the tool.

Here's a slight deviation.

I have 1G of memory, but VM is taking up 2G of disk space. I've noticed when
I've been one for many days and have had maybe 10-12 windows up, things slow
down. This is particularly true if I bring up Word 2003. Right now I have 4
browser windows open, and one mailer window, and rebooted after about 5 days
of continuous use. I brought up Word 2003 in about 5 sec. Before I booted it
was taking 2 minutes. Memory leaks or just too much work out of VM?

Probably the paging. If the hard drive seems to run a lot when you have
slow performance then it is the paging file. With 1GB of ram you should not
see a lot of paging in typical use. If the way you use your computer is
resulting in a lot of paging then the solution is additional ram.

Well Upgrading More Memory Will Make A Difference But It Depents Wht Program Ur Using And Usage .some Time U Have No Programs Opened Still The Memory Says Its Being Utilized Full..its Could Tht Some Programs Are Still Running In The Background Without Ur Knowledge..so Best Way Is To Disable All Startup Programs Form Loading Which Are Not Required..at The Same Time U Can Increase Ur Virutal Memory
by
1. Click Start, right-click My Computer, and then click Properties.
2. In the System Properties dialog box, click the Advanced tab.
3. In the Performance pane, click Settings.
4. In the Performance Options dialog box, click the Advanced tab.
5. In the Virtual memory pane, click Change.
6. Change the Initial size valued =ouble size of the memory and the Maximum size value+3times more than the initial zise to a higher value, click Set, and then click OK.
7. Click OK to close the Performance Options dialog box, and then click OK to close the System Properties dialog box.

Try Ctrl+Alt+Delete to select Task Manager and click the Performance
Tab. Under Commit Charge what is the Total, the Limit and the Peak?

You should be able to gather more information from Task Manager. With
the Processes tab open select View, Select, Columns and check the boxes
before Peak Memory Usage and Virtual Memory size. What are the figures
for the 6 processes using the largest amounts?

Open Disk Defragmenter and click on Analyse. Select View Report and
click on Save As and Save. Now find VolumeC.txt in your My Documents
Folder and post a copy. Do this before running Disk Defragmenter as it
is more informative.

Total 587572. Limit 13453234. Peak 669774.

Can't provide the six. The table keeps changing every second. Is there a
graph? CPU, CPU Time, Mem Usage, Mem Delta, VM Size. Six? PID/Image Name.
If I pause it, Tuner.exe is high on CPU=50. That's Radio Replay. System Idle
is high for CPU time=5:04:28, SeaMonkey(Mozilla) is high on Mem Usage=200M,
Mem Delta is 0 for all processes, SeaMonkey is high on VM Size=188M,

It's been 8 hours since I rebooted, and I only have about 5 windows open,
Radio Replay, Canon Zoom Browser, Paint Shop Pro, 2 Folders, Downloader.
Things seem OK. Word 2003 came up in 5 seconds. My D-drive is an internal
WD, 150G, and my E-drive is a USB 300G WDigital. C is 80% used. D is 86%
used, and E is 90% full.

Defrag says C should be defraged. Actually, all three!

Here are the three reports. Note despite the disagreement with drive
letters, they are the only three drives. C-drive is accurately named.

I've removed the folder references from the report. The two smaller drives,
particularly C, gets a lot of activity from me. The USB larger drive is once
and awhile. The two bigger drives have seen big transfers between each
recently. All done three weeks ago.

At the time you obtained the Commit Charge figures your system was
probably making very little use of the pagefile as the utility suggested
by Ken Blake would confirm. However, some of the programmes you are
using could rapidly increase the memory usage to more than your
installed RAM so the system resorting to use of the pagefile becomes
inevitable. An example is a graphics programme used to edit photographs
where the undo feature will hold large amounts of information in memory
until the editing is complete and the file saved. Another aspect is the
potential for memory leaks. In this case the memory is not released when
you close the programme. You need to restart the computer for the memory
to be released. Your comment about the speed Word 2003 loads after
restarting the computer suggests that memory leaks may be impacting on
your system.
http://en.wikipedia.org/wiki/Memory_leak

Memory leaks can occur with a particular version of a programme or occur
with successive versions so comments on particular programmes have to be
taken bearing that in mind.

SeaMonkey according to reports, uses a lot of memory and is blamed for
memory leaks. Googling on "SeaMonkey memory leak" produces interesting
reading. Do you have Netscape Navigator 8 or 9 (which is or was a beta)?
Investigating how individual extensions work might highlight a problem
area. There is a newer version of Sea Monkey to the one you are using:
http://www.seamonkey-project.org/

Other Mozilla projects e.g. Firefox are also known to contain memory
leaks.

What version of Paint Shop Pro? Doesn't this have an Undo feature? This
also seems to be blamed by some for memory leaks.

Radio Replay threw up a fixed memory leak. What version of Winamp do you
have? Bug fixed in v5.34

Avoiding unnecessary multi-tasking and leaving windows and programmes
open after use, will help to minimise memory usage. Shutting down at the
end of a computer session will help to minimise the impact of any
existing memory leaks.

To get the top 6 in Task Manager simply click on the Peak Mem column
head once or twice to sort the processes in the order you require. Note
I was asking about peak memory not CPU usage.

From your Disk Defragmenter reports I notice you are using VobBlanker.
This has left a multi fragmented 1 gb file in a temporary folder. Do you
know what purpose this file serves? Does it need to be retained? Will it
automatically be replaced with a like file if deleted the next time to
use VobBlanker. Large fragmented
files are often not easily defragmented by Disk Defragmenter. When left
as they are they can cause newly created files to fragment more rapidly
than they might otherwise do. You could try copying the file to another
partition, deleting the file on C, running Disk Defragmenter on C and
then copying the file back to C. Finally the delete the file on the
other partition. Use the Copy command rather than the Move command.

Earlier you complained that your pagefile was overlarge at 2 gb. You
have obviously reduced it to 384 mb. This could be a mistake and you
should consider reinstating it to at least 1 gb maximum. Many will
recommend you changing to "Let Windows manage". If you reduced the size
to create free disk space there may be other better ways to achieve your
objective. One, there are others, is detailed below.

The default allocation to System Restore is 12% on your C partition
which is over generous. I would reduce it to 700 mb. Right click your My
Computer icon on the Desktop and select System Restore. Place the cursor
on your C drive select Settings but this time find the slider and drag
it to the left until it reads 700 mb and
exit. When you get to the Settings screen click on Apply and OK and
exit. This could create a further 7 gb free space.

Disk Defragmenter will be grumbling at only 14% free disk space on D.
The fragmented files listed may defragment if you run Disk Defragmenter
a second time. You should, however, consider either deleting files no
longer needed or backing them up to DVD/CD to creating more free disk
space. Equally the same point applies to your E drive.

It is unusual to see the MFT record for a partition / drive showing up
with more than 3 fragments. You are showing 5 on C and 6 on E. Running a
disk cleaner, either Disk CleanUp or cCleaner to remove unneeded
temporary files, may restore the MFT on the two drives. A problem with
MFT files is they only ever get larger; never smaller!

Is System Restore monitoring your D and E drives. It should only be
monitoring only your C drive! I cannot tell from the information you
have posted.

Have you tried using cCleaner to clean up your disk?

An alternative is cCleaner (freeware) which does a more thorough job
than Disk CleanUp.
http://www.ccleaner.com/ccdownload.asp
http://www.ccleaner.com/

With any cleaner you need to proceed with caution. To be safe you
should create a restore point before using cCleaner. cCleaner also
offers backup before removal.

When using cCleaner think twice before checking Autocomplete Form
History under Internet Explorer. You do get a warning but this one has
irritating consequences. You may need to restore your system's
recollection of passwords after use so keep a record off computer so
that they can easily be re-entered.

Leave the Scan for Issues option alone.

You still need to remove System Restore points via the More Options tab
in Disk CleanUp.

Good stuff. I've printed it out, and will look into this further as
mentioned below.

Peak mem use is 266M by seamonkey. Google desktop 110M, dfrgnfs 71M,
explorer 43M, Tuner 49M. Forgot to look at utility. It's now bookmarked, at
least.

I'm using both PSP 7 and 9. Currently, I've been playing with 7, but usually
am on 9.

I'll check the 1G file.

I did MS defrag my 300M HD (D-drive). That was an interesting experience. I
had deleted large folders some weeks ago, and the analysis graph showed that
plainly. I let it rip for 3-4 hours and it had only gotten to 25% complete.
Around then, I started to get concerned about overworking the HD, so paused.
Several hours later I resumed, and all seems well on that device. Onward to
the next biggest HD, then to the c-drive.

I made no overt change in the page file. Maybe I misread the value. Page
file = VM size, right?

I ran into the 14% limit, and just deleted several Gb.

Ah, those memory leaks. I probably created a few in my programming days long
ago. I've forgotten the name of the test tools that will seek them out (in
the development stages). Good use of Google to see what's going on with the
commercical programs. I'll follow up on the ones you pointed out.

I'll follow through on the C-drive suggestions, 12%, ...

MFT files. Hmmm, OK. I'll look into the cleaner programs. System restore
points. monitoring I've never heard of. Is it used in connection with
backups or system failures (power outage)?

I'll send you the the complete three reports privately later today.

Thanks.
 
W

W. Watson

Ah, the "private" mail I sent you got bounced. @nospam will do it every time.

Anyway, I've managed to defrag all three drives and they look good. I'll do
what I can about other matters like memory leaks, and folders and files that
are of no use any longer.
