Therefore, when the total memory capacity is below 256MB, the minimum value of virtual memory is set to 1.5 times times; above 512MB, set to half of the memory capacity, between 256MB and 512MB is set to the same value as the memory capacity, you can put the initial size and

The maximum value is set to the same to avoid the system changing the paging file size frequently.
