Virtual memory is not for virtual physical memory, but for temporary storage of data. If the demand for memory is greater than the total amount of physical memory, then no matter how large the virtual memory is, it is useless. Computer memory is too low, the fundamental solution is to increase physical memory to be smooth. Virtual memory doesn't work in mechanism, even if it does, it is 100 times slower than physical memory, and it has no practical effect.

When running a big program or a big game requires more memory than free memory but less than the total physical memory, the data in the memory will be temporarily put into the virtual memory on the disk to release the physical memory to run the game. After you quit the game, you will read the contents of virtual memory and put them back into physical memory. In other words, the total amount of virtual memory and physical memory should be similar, but considering the possibility of compressing data, it can be slightly larger than physical memory.

Factors affecting the running speed of computer

First, there are too many plugins.

Solution: Delete infrequently used plug-ins regularly.

Second, there are too many programs loaded at startup.

Solution: Close the boot loader.

Third, the system disk is congested

Solution: Reduce the number of applications installed on the system disk and help the system disk slim down in time.

Fourth, there are too many desktop icons.

Solution: Manually delete uncommon desktop icons.

Verb (short for verb) is out of virtual memory.
