See what you do, if the general use, do not have their own modulation, virtual memory to improve the speed is not very large in fact, the memory bar is also very cheap, plus a try the best.
According to Microsoft, the minimum value of a virtual memory swap file should be 1.5 times times the size of memory, but if the memory is larger, it takes up a significant amount of space. Therefore, it is recommended that the memory capacity below 256MB, set to 1.5 times times; above 512MB, set to half of the memory capacity is fully feasible; between 256MB and 512MB is set to the same value as the memory capacity. If you have more than 1GB of RAM, you may not need to set up a virtual memory Exchange file at all.
Of course, setting the minimum size of the paging file to be larger than these theoretical values has no effect on the entire system's operation, and should be better, and the only loss may be that the free space on the hard disk is reduced accordingly. If your hard disk space is more tense, when you set the paging file, you can make it not less than 3/4 of the system memory, so you can ensure that the system more stable operation. If you need to load and unload large software frequently and do a lot of tasks, you'll still be safe with the defaults, or you'll cause system crashes regularly.
In principle, it's better to increase the physical memory. It doesn't make much sense to change the virtual memory size, because it's also a physical process for storing, reading, and processing.
If you really don't understand, you can let the master of optimization set
