Have you ever heard of virtual memory? If not, this is the article that can help you learn some useful knowledge about it.
If you have heard that, you also can get helpful methods to deal with it.
So-called virtual memory means that the system applies certain hard disk space as memory when the physical one is insufficient.
But since the transmitting speed of disk is much slower than that of memory, that is why you may feel it is not so fast to use it.
You should set virtual memory according to the size of memory and usage of computer.
If you set the value too large, it can produce many fragments and influence computer speed seriously; if too small, it is far from using and then system will remind you the it is too low.
In the default condition, you can let Windows allot virtual memory automatically.
It can adjust memory dramatically based on actual usage.
Normally, it is one and half to three times than that of physical memory.
And the minimum value is one and half to two times and two to three times of maximized one.
And I advice you not to put the it which you set and the system set in the same partition.
Memory is changing dramatically.
So disk fragments are easily produced in the C disk and affect system running speed.
Therefore, you had better set virtual memory in larger disk that you do not use frequently, such as D or E disks.
By doing this, the hourly read-write operations to hard disk can hinder the system speed.
As a result, it is a must for you to set it like this.
As for setting that, you can right-click "My Computer"-"Properties"-"Advanced"-"Performance" and click "Advanced".
In order to change virtual memory, you can change C disk to D disk and choose "Customize" to set perfect value for you computer.
