Squeezing every drop of IO out of the system was the order of the day

I have found that using RAID0 has extended the life of my smaller discs and I now get stunning speeds from simple 7200 rpm 32mb cache because there are multiple channels to each bit of data

I trust not to far off thread, please remove if it is
All I'm saying is it's way past time for some meaningful system settings in Windows. It wasn't an attack on you. You've done what can be done with the settings available.

Filtering swap through the file system after all this time shows they only care about the next glitzy looking thing that will be abandoned when the buzz wears off(see Gadgets thread.)

edit: I mention it because what you did with the page file on its own partition is emulating a swap partition. The system should just give you the option. It's not like it's some arcane newly-discovered theorem. It's been in use on other systems for a long timne.


And why does a system dump have to have a page file? Seems to me OS/2 used a dump file way back in the 90s.

All I can figure is the guys from DEC who wrote NT are dead or retired and they haven't been replaced with anyone of similar competence.

Oh I agree Miles...windows is focused on the general audience, not the ideal situation for each one's experience (it would seem to me at least) and $$$-wise it makes sence...so i cant say i blame them.
(NOT MS EMPLOYEES IN GENERAL NECESSARILY - just the Co. conceptual design)

but we may be getting WAY off topic but you're absolutely right - focus on making these types of things simpler to do... I think more people would appreciate it than the "numbers" say would.....

My reason for using this process is an attempt to reduce the size of an Image File of my C: Partition .
It is possible to have a Page File on multiple partitions. It is not recommended to have your paging file on a different partition which is on the same hard drive as Windows. The reason is your drive will have to work harder because it must read both partitions:
1) The first partition with Windows
2) The other partition with the page file

Your hard drive would have to constantly switch between reading your Windows partition and the partition with the page file. This will reduce performance and increase wear on your hard drive.

However, if you have multiple separately running hard drives (nonRAIDed) it is actually recommended to create your page file on your nonWindows (nonO/S) running drives. If you have 2 drives, you can create your page file on the first partition on the second drive and remove the page file on the first drive. If you have 3 drives, you can create half your page file on the first partition on the second drive and create the other half of your page file on the first partition of the third drive. Of course, you would do this using the "Advanced System Properties" dialog, not Windows Explorer.

This will increase performance because your Windows hard drive will not be forced to deal with your page file. Your controller can deal with multiple hard drives much faster. If you have 3 hard drives, your 2nd and 3rd drives will divide the work and increase performance even more. I have 3 hard drives and have done the above. I have noticed a performance increase.

When I make a backup, I simply make a copy of the Windows partition using my partition software. I do not use the Windows 7 backup program. I do not know the effects placing the page file on other drives would have on the Windows 7 backup program.

The following can be used for reference:
1) Microsoft's Tech·Ed Europe 2009 Pushing the Limits of Windows video at 33min:00sec to 36min:33sec regarding page file size

2) Windows 7 Inside Out on page 726 regarding performance over multiple HDD's

You might want to download the "Pushing the Limits of Windows" WMV video file and view the entire video. It has other information you will find useful. In fact, you might want to download and view all of the Mark Russinovich videos. They have a lot of useful information. You should also download and install his free Sysinternals utilities (now bought by Microsoft), particularly Process Explorer and Process Monitor.

Good luck

TL;DR, if you have a single disk, leave the pagefile alone, ALL imaging softwares around ignore the PF, so its useless to mess with it to decrease image size.

The only thing I would add to this post is:
  1. Forcing the Page file to have the same maximum and minimum page file size removes an problems of Page File fragmentation however;
  2. Ensuring the PC has the correct amount of RAM is the most effective way of speeding up the system as the Page File is then unlikely to be accessed

I agree, there's no reason to move the PF on a one HDD sys! But just to clarify, MOST imaging SW will not copy the PF, although some apps will, offer a full bit-by-bit raw-image of the ENTIRE drive which, does in fact copy the PF, HF, REGF's, SYSV, etc. irregardless of special file attributes/status. I don't remember ever needing it with a win 7 sys, but I see no reason why it would differ from vista/xp/etc.
