There has always been a saying that physical memory is 8G, virtual memory is useless to turn off, but this is not true, because the virtual memory in the Windows operating system carries a lot of functions beyond the function of the page file.
In many cases, Windows systems need to use virtual memory to perform specific operations, such as software memory error correction, greater latitude address confusion, larger process fork cache, and the like to improve memory hit rate and system stability.
Large applications such as PR and AE are very memory intensive. When running, virtual memory can work in a more coordinated manner. Turning it off can reduce system reliability and performance.
Take my computer as an example. I installed Samsung's 970EVO PLUS SSD and 16GB of memory. Because I usually use PS to repair a picture at the company, the rest is basically the form text requirement, so I Instead of customizing the virtual memory separately, the system automatically manages the paging file size.
Virtual memory has higher 4K performance and seek time requirements for the system hard disk, and when the virtual memory is set on the system hard disk, the performance of the general SSD will be slowed down.
Because the data exchange between the memory and the hard disk will make the system slow down. For example, in the case of Google Chrome, if you open multiple web pages at the same time, the normal browsing of this webpage is smooth and no problem.
But if you switch to a web page, there will usually be a white screen. This requires closing the browser or waiting for a while to continue.
Therefore, even after a very normal computer has replaced a better SSD, the exchange speed of virtual memory and memory has been significantly improved, and we can obviously feel that the speed of the computer running program will soar.
The current physical memory is generally 16G, and our daily common data and very useful data are much larger than this number, so the very useful data is not suitable for occupying space all the time, we can choose to put it into the paging file. Then, leave the physical memory for use by other processes.
Indeed, turning off virtual memory allows the Windows system to map all data to physical memory. It does allow a small number of processes that use less memory to achieve a range of performance improvements, but disable virtual memory partners, you are willing to put up more open. Several web pages or a few large pictures with PS are prompted to run out of memory?
So my point is that no matter how big the physical memory is (I think the most common is 32G), the existence of virtual memory is useful (of course, if your hard disk space is insufficient and there is no upgrade budget, then I still recommend that you close it. ), if you are not willing to study it in depth, then set it to system management and hand it over to Windows.
