How to use memory efficiently

Method 1: Adjust the size of the cache area. The so-called cache refers to the system adopting the "pre-reading" technology when reading the data on the disk or the optical disk, that is, pre-reading the data to be read into the memory cache, so that the CPU is The data is read faster in the cache, which increases the speed of operation. Setting the cache in memory can significantly speed up the reading of data. Windows can automatically set the size of the cache according to the size of the memory. Of course, users can also set the size of the cache in memory according to their own memory to optimize the use of memory. The method is as follows:

Right-click "My Computer" on the desktop; click "Properties" in the pop-up menu; click the "Performance" tab in the pop-up window; click " File system button; click the "hard disk" tab; drag the "read-ahead optimization" adjustment lever to set the pre-reading condition; set the system to use the cache ratio in the "main computer use" column; if the system's memory is more More, you can choose "network server", so the system will use more memory as a cache; in the CD-ROM label, you can directly adjust how much memory the system uses as a CD-xviii) ROM disc read and write cache, pay attention to Select "Four-speed or higher speed" in "Best Access Method", so the system will set the size of the cache according to the situation; you can also adjust the adjustment bar in the "Applied Cache Size" column, xxii) Append the cache.

Method 2, monitor memory. No matter how big the system's memory is, it will always run out. Although there is virtual memory, because the read and write speed of the hard disk cannot be compared with the speed of the memory, the large and frequent use of virtual memory will make the computer operation unbearable. So when using memory, always monitor the memory usage. A system monitor is provided in the Windows operating system to monitor memory usage. There is also an easy way to select the "Help /About Windows" menu in any file window. You can see the current memory usage in the open window. Generally, if only 60% of the memory resources are available, this is You should pay attention to adjusting the memory, otherwise it will seriously affect your running speed and system performance.

Method 3, release the memory in time. If you find that the system has less memory, pay attention to freeing up memory. The so-called release of memory is to release the data residing in the memory from the memory. The easiest and most effective way to free up memory is to restart your computer. The other is to shut down running programs that are not in use, including programs that run in the background. Usually, you should develop such a good habit and close programs, files or windows that you don't use at any time. Some applications can't be closed in the normal way. In this case, you need to perform a hot start, such as pressing "CTRL+ALT+DEL". Also note that if a picture or image is stored in the clipboard, the picture or image is occupied. A lot of memory, then just cut and paste a few words, you can flush the original image on the clipboard in the memory, thus releasing a large amount of memory it occupies; also, printing files in the background will also take up a lot of Memory space.

Method 4, optimize the data in memory. In Windows, the more data that resides in memory, such as the shortcut icons on the desktop, the icons in the taskbar, and the time in the system tray, all occupy memory resources. Therefore, the shortcut icons on the desktop and in the taskbar should not be set too much. If the memory resources are tight, you can consider optimizing these projects, and try to use a variety of background-resident programs, especially badly designed programs, which consume a lot of memory resources. When you are operating your computer, do not open too many files or windows, or open too many data files in the program. If it is open, close these files or windows when you no longer use them. In addition, after using the computer for a long time, if you do not restart the computer, the data arrangement in the memory may be confusing and the performance of the system will be degraded. Then you should consider restarting the computer.

Method 5, improve the performance of other parts of the system. The performance of other parts of the computer also has a greater impact on the use of memory, such as bus type, CPU, hard disk, video memory and so on. If the memory is too small and the amount of data displayed is large, it is impossible to increase the speed of the system and the performance of the system. If the speed of the hard disk is too slow, especially the average seek time and speed is too slow, it will seriously affect the read and write speed and performance of the system's virtual memory, resulting in a decline in the performance of the entire system.
