How to set the virtual memory size of Windows 7

Q: How to set the virtual memory of Windows 7?
A: Virtual memory is only a supplement to the real lack of memory, so do not deify, virtual memory read and write performance (ie hard disk The read and write) only has a few tenths of the real memory performance, and it is very harmful to the hard disk! If you can not use it, you can use it less. The principle is enough to use + a small amount of margin.
Misunderstanding 1: Virtual memory should not be located in the system disk C disk (system disk), but should be set in other non-system partitions.
Answer: Wrong! Because the C drive is the default system disk, the hard disk read and write most frequently is the system file and page file. What is the most time-consuming operation of hard disk reading and writing? It is the head positioning! The head positioning in the same partition is undoubtedly more time-saving than the long-distance positioning across the partition! So, the virtual memory in the system disk (system default Value) is the fastest and most efficient implementation.
Myth 2: The optimal value of virtual memory is 1.5-3 times the memory capacity.
Answer: Wrong! It should be judged according to the actual use. Especially the popularity of large memory today. Memory usage See the task manager's memory column. Generally 1GB memory, according to the actual memory usage, you can set the virtual memory to 128-1024MB (the sum of memory + virtual memory is generally 256-512MB higher than the normal occupancy). Usually, people who normally occupy hundreds of megabytes can even disable virtual memory (software-limited software can set a small amount of virtual memory, such as 16-128MB).
Memory is 2G and above, you can generally disable virtual memory (software limited to a small amount of virtual memory, such as 16-128MB). Some people who do use a lot of memory, such as playing large 3D games, making large pictures, 3D modeling, etc., and receiving the system memory shortage warning, need to set the virtual memory as appropriate.
Misunderstanding 3: The bigger the virtual memory, the better.
Answer: Wrong! The virtual memory is too large, which wastes disk space and increases the time for head positioning, which reduces the system execution efficiency and has no benefit. Correct setting can save 256MB-4G space (depending on memory size)
Take Windows 7 as an example, set virtual memory steps:
Computer right button, properties, advanced system settings, performance, settings, advanced, virtual memory, Customize the size, enter the number and click “Set”, OK, exit and restart the system.
