What does it mean that the page file has been used 230MB?

It's virtual memory.

XP is called PF.

If there is 2 GB of memory and 1 GB has been used, then only 1 GB is left available, and closing infrequently used programs can reduce memory usage and improve the response speed of the computer!

As soon as the system is turned on, it will occupy a part of the memory space, XP is about 400M, Win7 is about about, it is impossible to use memory at all, the size of the memory also affects the response speed of the computer, the larger the memory, the better.

Win7's system eats the most resources,Especially memory,Generally, win7 is best used4G memory will be smoother,win72G memory is not enough,Open a few programs on the full load,At that time, the computer was very difficult,If you don't do it well, it will crash,So it is recommended that you don't open too many programs at the same time,Win7's response will be slower。 It's more personal, though.

You can use the security guard to optimize it, optimize the program that does not need to boot automatically, you can save some resources, and don't install multiple antivirus software, not only useless, but also a great waste of resources, and may conflict, it is recommended to use the same series of antivirus, like the 360 set is very good.

The Windows operating system uses virtual memory to dynamically manage runtime swap files. In order to provide more memory capacity than the actual physical memory for use, the Windows operating system takes up a portion of the space on the hard disk as virtual memory. When the CPU asks for it, it reads the data in memory first.

When the memory capacity is insufficient, Windows writes the data that needs to be stored temporarily to the hard disk. So, the size of the computer's memory is equal to the actual physical memory capacity plus the size of the "paging file" (i.e., the swap file). If needed, Paging Files uses all available space on your hard disk.

Here's a brief rundown of virtual memory:

If your computer is running at a lower RAM and immediately needs more RAM, Windows uses hard disk space to emulate your system's RAM. This is called virtual memory, often referred to as a page file. The page file is similar to Unix's "swap file".

The default size of the virtual memory page file named "is times the RAM size on the computer.

When Windows was originally designed to use virtual memory, it was designed because physical memory is expensive, generally not exceeding 128MB capacity, and requires hard disk space for temporary buffering - that is, you should compare how much physical memory you need when you apply to the memory you actually have, and if you actually have less memory than the application peak, you will run into trouble.

Generally speaking, if you want to perform data-intensive tasks such as large plane drawings and 3D animation rendering, you should not disable virtual memory. If you often have to print documents with a large number of **, disabling virtual memory can also cause errors in the program. Because software such as word needs to generate buffer files before printing, and then transfer to the printer, when the size is large and the resolution is high, the buffer capacity required is also very large, and the author used to help advertising artists to produce design drawings, and encountered the situation of printing a picture to generate nearly 300MB temporary files. Because Windows and the application itself also require a certain amount of memory to run, if you are in a 512MB configuration and disable the virtual memory, it is very likely to report that the virtual memory is insufficient, and the forced exit will cause a waste of printed paper and ink.

Therefore, it is important to decide whether to disable virtual memory based on the context in which the task is applied. Even if the virtual memory size is fixed, you must be cautious, otherwise when running large application software, the virtual memory will appear insufficient prompt, and the whole system will become very slow due to the extremely high CPU occupancy, and it will not be so convenient to change it at this time.

It is also recommended that LZ leave it to the system to manage the virtual memory by itself, because poor settings will also cause the system to slow down.

Above, I hope that LZ is happy to use.

It is the memory you have already used, for example, if you have 2G in memory, and you have used 1G, then there is only 1G left in the remaining available programs, and closing programs that are not commonly used can reduce the use of memory and improve the response speed of the computer!

It is estimated that you are using the QQ space application to encounter it, it doesn't matter, ignore it.

A page file is a piece of space carved out of the hard disk, and yours is a 1054M page file that is equivalent to memory, but slower than memory. To run the program, you need to read the program into memory first. But in many cases, the memory capacity is too small to be sufficient, so it needs to be stored in the page file area of the hard disk.

Therefore, the page file is a virtual memory file, and its size depends on the number of open programs and the minimum and maximum value of the page file you originally set, which is constantly changing, sometimes only a few tens of meters, sometimes reaching more than 600 meters.

Due to the large consumption of memory, some large-scale software also opens up a part of the hard disk space as a buffer, and the entity of this part of the hard disk space is the page file created by the software, such as Photoshop. This design relieves the pressure on the system's scheduling memory and increases the speed of the software.

Page files are virtual memory that uses hard disk space when running programs, not all physical memory.

Memory plus virtual memory Yours and its virtual memory settings are too few.

Page files are virtual memory!

You have to look at the configuration can right-click on my computer, properties, you can see the cpu and memory,

The 230MB of available memory for the system and the 215MB of memory to run the software are too small. Can't install more software. Running will also get stuck.

It's like the memory and hard disk in your computer. But your configuration is so low.

The memory is too small to fit a lot of things

For example, some people have to run large programs such as 3DMAX and Photoshop, while some people may just type and play small games, so the requirements for virtual memory are not the same, so we need to accurately set the value of virtual memory space according to local conditions.

First, set the "initial size" and "maximum value" of the virtual memory to two identical values, such as 500MB.

Then open "Control Panel Management Tools Performance", in the "Performance" dialog box that appears, "Performance Logs and Alerts" in the left column, select "Counter Logs" under it, right-click in the blank space in the right column, and select the "New Log Setting" option in the right-click menu;

In the name field of the pop-up dialog box, fill in any name, such as "Virtual Memory Test". Click the "Add Counter" button in the window that appears to enter the next window;

In this window, open the drop-down list of "Performance Object", select "Paging File", select "Select counter from list", and select "%usage peak" in the lower column. Select "Select example from list", select "total" in the lower column, and then click "Add Close" to finish.

In order to view the log files conveniently, you can open the "Log Files" tab, select "Log File Type" as "Text File", and finally click the "OK" button to return to the main interface of "Performance".

In the column on the right, you can find an additional "virtual memory test" item, if the item is red, it means that it has not been started, click on this item, and select the "Start" option in the right-click menu.

Next, run some of your commonly used applications, after running for a period of time, enter the default directory "perflogs" under the system partition where the log file is located, find "Virtual Memory Test and open it with a notepad program (Figure 6), in this content, we look at the penultimate value in each column, this value is the virtual memory usage ratio, find the maximum value of this value, such as "46" in the figure, multiply 46% by 500MB (the virtual memory value set earlier), The resulting value is 230MB.

With this value, you can set the initial size to 230MB, and the maximum value can be set freely according to the amount of disk space, so it is generally recommended to set it to 2 to 3 times the minimum value. In this way, we can build virtual memory more accurately, so that our favorite device can run more smoothly and efficiently.

If it's a simple setup, it's not difficult, and if you mean you want more memory, it's just plugging in a memory module. Here's how to do it. Right-click the My Computer-Properties-Performance-Virtual Memory button, the virtual memory settings window will pop up, click "User Specify Virtual Memory Settings", and then enter the values in the "Minimum" and "Maximum" text boxes.

That's it.

This means that 198 (MB) of the page file has been used and 41 (MB) is available. About Virtual Memory:

1. The so-called virtual memory (page file) is to use a part of the hard disk space as memory when your physical memory is insufficient. Physical memory refers to the size of the memory module that is plugged into the motherboard of your computer, such as 256MB and 512MB.

2. The specific value of custom virtual memory is determined according to the size of your physical memory, generally 128MB physical memory is set to 2-3 times, 256MB is set to multiple, 512MB is set to 1-times, 1GB is set to be doubled or set to automatic. For example, if your physical memory is 128MB, the "initial size (MB)" of your virtual memory can be considered 256, the "maximum value (MB)" can be considered 384, and the maximum value for playing games can be set to a larger value, such as 512.

3. The specific steps are as follows: right-click "My Computer" Properties Advanced Performance Settings Advanced Virtual Memory Change Select the partition where the virtual memory (page file) is stored Custom size Enter "Initial Size (MB)" and "Maximum Value (MB)" in the numeric box Set OK.

Fourth, the partition where the virtual memory (page file) is stored must have enough space, and the hard disk resources are insufficient, resulting in insufficient virtual memory; It is enough to set virtual memory in one partition of a computer, and there is no need to set virtual memory in other partitions, which is generally located in partition D close to partition C where the system is installed.
