To Page Or Not To Page? – No Paging File Brings Backup Programs To A Crawl


virtual-memoryI like to optimize my system using tweaks and tips I find online. Sadly, most of these tweaks and tips either don’t work or if there are any benefits we are talking about fractions of a second that we cannot perceive one way or the other. One tweak that comes up a lot is the setting of the Paging or Virtual Memory. That is, when your computer runs low on actual memory your computer uses your hard drive as virtual memory (basic explanation).

Back in Windows XP days, more than once I came across the issue of computers grinding to a slow pace with a message of “running out of memory and Windows needs to adjust the virtual memory file”. Setting this manually in Win XP was a must. I recently came across information online that claims that computers with at least 4GB of RAM don’t really need a page file. So I decided to try it out and see what happens. I have 4GB RAM on a Win7 Home Premium 64bit version.

Go to: Control Panel – System – Advanced System Settings. Open the Advanced tab and then click the Settings button in the Performance box. Then again open the Advanced tab and in the Virtual memory box click the Change button.

Uncheck (if checked) Automatically manage paging file for all drives. If you want to keep it set but customize it yourself click on the little circle by Custom size then set both Initial and Maximum to the same size.

This is one of the more popular methods to determine size:

(1024 x (amount of memory on system)) x 1.5 – so I have 4GB of memory
1024 x 4 = 4096
4096 x 1.5 = 6144 so I set the Initial and Maximum to 6144MB


Another option is to look down below for the Recommended size and set both Initial and Maximum to that size. Then click on the Set button to finish. Click on No Paging file to disable this option as I did and then press Set.

I did not notice any difference in the operation of my computer until I decided to backup my system by creating a System Image. I use a program called Macrium Reflect. It usually only takes about an hour to back up my 54GB of usage on my 500GB drive. But now it was claiming that it was going to take up to 10 hours!

I thought there was something wrong with the program first until I tried Windows 7 built in backup program. I use this regularly too.

It actually took longer. I had to let it run over night. I was sure that disabling the paging file was what was causing the slowdown. Enabling it again proved my point. So it seems that these two backup programs are dependent on the paging file if you want to get it done in a hurry. Since I try to do a monthly image backup, I’m keeping it enabled.
