1, the so-called virtual memory is to use a part of hard disk space as memory when your physical memory is not enough. Because virtual memory is used with the system running, it is best to set up virtual memory with the system in partition C, but virtual memory changes dynamically with the use, and disk fragmentation is prone to occur in partition C, which affects the running speed of the system. Weigh the pros and cons, or set the virtual memory in other partitions with large remaining disk space, such as D, which is not commonly used. In a computer, it is enough to set virtual memory in one partition, and it is not necessary to set virtual memory in every partition.

2. Because the transmission speed of hard disk is much slower than that of memory, the efficiency of using virtual memory is slower than that of physical memory. It is best to increase physical memory when playing large games. The setting of virtual memory is mainly based on the size of your physical memory and the purpose of your computer. Too large a setting will lead to a large number of fragments, which will seriously affect the system speed. Setting it too small will not be enough, so the system will prompt you that the virtual memory is too small, and the actual value needs to be adjusted several times before it can be determined.
