If the virtual memory is set too much, there will be no adverse effects?

The size of virtual memory is closely related to the size of your memory. Generally speaking, the minimum value of virtual memory should be set to a multiple of your physical memory capacity, and the maximum value should be set to a multiple of the physical memory capacity. There's no harm in setting up too much virtual memory, but it's a wasted disk space.

Disadvantage 1: Occupies space on your hard drive. When the memory module capacity is insufficient, the system calls the hard disk space to use as virtual memory. The higher the virtual memory setting, the more space the system allows for the virtual memory to occupy on the hard disk.

Disadvantage 2: Accelerate the mechanical damage of the hard disk. When the memory module capacity is too low, the system will frequently call the hard disk space to use as virtual memory. Frequent reading and writing of the hard drive will accelerate the mechanical damage of the hard drive, which will reduce the life of the hard drive.

Virtual memory is a supplement to physical memory, when the physical memory is insufficient, the system will divide a space on the hard disk into memory to ensure that the program can run normally.

Therefore, the function of virtual memory is to ensure the normal operation of the program, but it has a negative effect on performance.

Since the virtual memory is placed on the hard disk, limited by the slow speed of the hard disk, when the system uses too much virtual memory, the system efficiency will be seriously reduced, and the hard disk will often spin wildly, which is why the system will slow down if the physical memory is too small.

As a rule of thumb, the specific settings are as follows:

If the physical memory is less than 2 GB, the virtual memory is set to be 3 times the minimum and maximum, for example, if the memory is 1 GB, the minimum and maximum virtual memory is 3 GB.

When the physical memory is 2 GB, set the minimum memory to 2 GB and the maximum to 4 GB.

When the physical memory is 4 GB, set the minimum to 1 GB and the maximum to 4 GB.

When the physical memory reaches 8G or more, the minimum is 1G and the maximum is 4G.

In other words, it is recommended to keep the minimum value of 1g, and the maximum value can be arbitrary, because the maximum value is actually a cap value, which will not cause occupation in practice, but it is not recommended to have the same value as the minimum value.

Finally, it is recommended to put the virtual memory in the C drive, because the C drive is the fastest area in the hard disk, as long as the C drive is large enough, theoretically everything is best in the C drive.

It is not recommended to put it on other disks, and do not do stupid things like setting virtual memory on each disk.

If it's too big, it wastes hard disk space, and it's easy to generate fragments, causing the system to slow down.

There is no harm!

When the memory is insufficient, the system calls virtual memory! It's just slower than a memory module!

It doesn't hurt. If there is a downside, it takes up space on your hard drive.
