如果您的计算机开始在几个月用法以后减速，那里您能做对您的设置将帮助增加您的计算机表现的两三次要变化。 扭捏窗口是根本得到最高性能为您的计算机。 在一台快速的计算机，如果设置是不正确的，计算机将不足执行。
虚拟内存设置：
当它填满物理RAM时，虚拟内存为您的计算机是Windows使用的硬盘空间。 假设您有有RAM 256MB的一台计算机，并且您立即跑也许需要总共记忆400MB的几种应用。 窗口在硬盘将填满256MB然后使用自由空间存放休息。 这称页式文件或虚拟内存和窗口将增加并且减少这个文件的大小如需要。 写给盘比文字很多时间花费对物理RAM，因此，当窗口使用页式文件时，计算机性能贬低。
所以您总将听见人问是否有足够的RAM，因为更多您有的RAM，越好的您的计算机性能将是。 然而，我们可以也扭捏虚拟内存设置，以便页式文件没得到分割，并且，以便窗口不必须增长或收缩页式文件的大小，其中之二将造成计算机减速，特别是在更旧的机器。
默认情况下，窗口使用引导分区(包含您操作系统的文件)的分开，并且推荐它设置大小到1.5倍您有的相当数量RAM。
要改变虚拟内存设置，去开始，控制板和点击 系统. Click on the Advanced tab and under the Performance box, click Settings.
On the Performance dialog, click the Advanced tab and then click Change under the Virtual Memory heading.
Now you’ll see the Virtual Memory settings as shown below:
Here are the rules for setting your paging file correctly:
To get the best performance it is best to create a paging file on a different partition than the boot partition (the drive that contains that operating system, which is usually the C drive) and to also create it on a separate hard drive. In this way, Windows can handle more I/O requests because the paging file will not have to compete with the system folder that needs to be constantly accessed as Windows runs.
The only problem with completely moving the paging file off the boot partition is that Windows uses the page file to write out debug info in case your computer crashes with blue screen of death STOP error. This is important for machines that have critical data, but for the average user, this is not a big deal. If you get the blue screen of death, it’s not an easy process at all to get to read the file and even if you can, it can be quite complex. But if you have enough space, then you can leave the paging file there.
So the best solution is to create on paging file on the boot partition that will take care in case of a crash and create another paging file on a separate partition on a DIFFERENT hard drive preferably. If you only have one hard drive on your computer, then just create another paging file on a different partition. Windows automatically uses the paging file that is on the less accessed partition using an internal algorithm.
Even more ideal would be if you could put the paging file in it’s own partition with no other data. This ensures that the paging file will never become fragmented and hence performance will be better. If it’s on a drive that has other data and the paging file must be expanded, and if there is other data in the way, the file will become fragmented.
Another way to reduce fragmentation of the paging file is to set the initial and maximum sizes to the same number. What this does is ensure that the file does not grow or shrink and therefore will not fragment. However, you should defragment the hard drive before doing this to ensure the paging file is all together on the hard drive.
So if you have only one partition, set the initial and maximum sizes to 1.5 times the amount of RAM you have. If you have more than one partition, select the boot partition and set the initial and max to 250MB. The reason for this is because it’s better to create another paging file on the other partition and create one paging file on the boot partition that’s just big enough for the mini dump file, which is 250MB.
On your second partition, select Custom Size and set the initial and maximum values to 1.5 times the amount of physical RAM you have. You can determine the amount of RAM you have by going to Start, Control Panel, and click System. You’ll see the amount of RAM at the bottom right.

Hi, I’ve tried doing all that you mentioned to increase my speed and increase my paging file. (I keep getting notices that I have no paging file) When I go through the steps, I’m showing that I’m adding a paging file (of 1536 mb), but after I re-start, it shows 0 mg. I’ve disabled everything on start-up as well, but it still takes a lot of time to boot. Can you help me. I no longer have a tech dept to support me, since I’ve retired. Thank you & God Bless, Walker
How do I set up a paging file on the boot system? How do I set up a paging file on my D hard drive? w.
nice article
Dear,
It’s a useful article that you have published. Thanks for that.
My situation is different. I have 4GB of RAM and I do not want to use PAGE FILE. I assume 4GB is enough for my WinXP to consume. What is your opinion : Should I stop using page file or I keep a 6GB of page file?
A reply will be apprecaited.

It is not neccessary to have a paging file as long as your system has enoughh pysical ram available. e.g.: if you have 2 gig of pysical ram installed and your system uses a max of say 1.2 gig of ram you can quite safely turn paging file off. The 1.5 x the amount of system RAM rule is very outdated -it was introduced with windows 3.1 when the average amount of RAM installed was around 128MB.
You do NOT need a paging file if you have plenty of physical RAM installed.
Hi,
I turned off using page file. Still, in Windows Task Manager’s Perofromance Tab, I see PF Usage 1.xGB.
As far as I know this ‘PF Usage’ shows amount of page file used. If I already turned off page file, how come it is showing 1.x GB of page file use?
Any idea? Thanks.
That’s an M$ error. PF usage is actually refering to the amount of RAM your system is using. A mistake M$ never bothered to fix.

Nice post, thanks for the info
Hi there I am an intern at an IT company in South africa and I have to better the perfomance of a PC i have been assigned to work on and the maths behind having to set the initial size of the paging file to 1.5 times the size of RAM is a bit difficult for me to understand. Plaese advise me!
For instance the PC I am working on has 1.11 GB of RAM.
