Optimizing Page-File Usage for PC with 2 Hard-Drives...???

By rajsdoshi ·
===================================
I want to Optimize Page-File Usage.
===================================

I have 3 GB of RAM,
and 2 hard-drives:
- C (65 GB) with 3 GB free space,
- D (75 GB) with 13 GB free space.

I was advised me to:
- Go to Control Panel > System > Advanced > Perf. Options > Virtual Memory
- Click on the Change button under Virtual Memory.
- click ?Custom? and SET the value at 1.5 times that of your system RAM.,
i.e. 3072 for me.

In the Virtual Memory dialog box, I see:
- for Drive C:
- (checked) Custom Size:
Initial size MB = 2046
Max Size MB = 4092
- (not selected) System Managed size
- (not selected) No Paging File

- for Drive
- (not checked) Custom Size
- (selected) No Paging File


Should I change any of the settings to Optimize Page-file Usage
or Change anything else to improve system performance ???

Again, Thank you for your valuable time.

You've got a couple of problems ...

by OldER Mycroft In reply to Optimizing Page-File Usag ...

Firstly, do you have 2 DIFFERENT HDDs or do you have 2 PARTITIONS both sitting on the same physical HDD ?

If you have 2 different hard drives, then your C drive is dangerously close to locking up. As a general rule of thumb for safety, each hard drive should have 15% of FREE SPACE (unoccupied by anything) which Windows will use on the fly for storing temporary files and which can also be used for moving files around during defragmentation runs.

Your C drive has less than 5% free space. This is already dangerously small and I imagine your system is already showing signs of slowing down?

This drive MUST have more free space, so you should run some utilities on it to free some space up. One thing you can do is to right click on the C: drive, select Properties and then click the button named Disk Cleanup. Let this run and it will tell you how much space you can free by ridding your C: drive of unnecessary clutter.

Until you have a minimum of 10% (preferably more than that) you will NOT be able to defragment the drive, because Windows won't have anywhere to move files to while it defrags the drive.

Your \ drive is hovering around the 17 to 18% mark but is approaching the free space mark of 15%.

If you do have 2 different physical HDDs, I advise that you move your pagefile from the C: drive to the drive - that way any activity in and out of the pagefile will not cause a bottleneck while programs and data are read/written to your operating system which is on the C: drive. It will also free up 2GB of much-needed space to this drive!

It is best that you allocate a pagefile to the drive, BEFORE you delete the pagefile on the C: drive.

When you create the pagefile make the upper and lower figures the same value, of 4608MB (as explained below)

_____________________________________

Your calculation for Virtual Memory is wrong. 3GB (3 x 1024) = 3072. Therefore your virtual memory should be 1.5 times 3072 which is 4608MB.

_____________________________________


To get rid of other unnecessary clutter which has probably built up on your system, download and install CCleaner from this link:

http://www.filehippo.com/download_ccleaner/

Click on the Download arrow in the green column on the right. Run CCleaner until it returns a clear list of results. Often you may have to run it recursively as it will pick up things on the 2nd or 3rd run that it missed on the initial pass.

You should run CCleaner for BOTH the 'Cleaner' then the 'Registry' functions, both found on the left hand column.

If you still cannot achieve 15% free space, you will have to consider deleting something from the hard drive or perhaps you could archive some files to an optical disc (CD/DVD).

Once you have an acceptable level of free space on each drive you should run a defragmentation pass on each (this will probably give you slightly more free space). It will also create free space that is 'contiguous' - not broken into bits of free space, but free space that is one big chunk. This is better for the operating system.

Free Up Drive Space

by TheChas In reply to Optimizing Page-File Usag ...

As a general rule, to allow for Windows to run properly, you want to keep your hard drives so that there is at least 20% free space.

Anything less than 10% free space slows down Windows significantly.

Next, as far as optimizing the page file (virtual memory) here is a link to a very good article on the subject.

http://www.aumha.org/win5/a/xpvm.htm

With 3G of RAM, you don't need as large a page file as the old rules of thumb implied. The 1.5 times installed RAM size for the page file goes back to Windows 3.1 when RAM was expensive and still measured in megabytes.

If you cannot clear at least 10 GB off of your C: drive, I would set up a fixed size 3GB virtual memory on the drive with no virtual memory on the C: drive.

If you can free up some drive space, I would configure a fixed 3GB virtual memory on the C: drive. (This allows Windows to perform a memory dump in the event of certain errors.) And then set up system managed virtual memory on the drive.

Of course, if this was my system, I would start by replacing both drives with 250GB or larger drives. But, not everyone stores as much data as I do.

Thank you for the feedback and the thumbs up.

It is always good to know when an answer has been helpful.

I hope you take the time to view some of the other resources at the aumha.org web page. I have found them to be very helpful.
