SWAP space is a technology used in the computer system for temporary storage memory pages. When the physical memory (RAM) is insufficient, the operating system will move part of the unremarkable memory page to the SWAP area on the hard disk to release the physical memory For other procedures. This method can effectively improve the system's response speed and overall performance, especially when processing large applications or games.

The role of SWAP

Relieve memory pressure: When the system memory use reaches the upper limit, the SWAP space can provide additional memory capacity to prevent the system from collapse or significantly reduce performance.

Accelerate processing speed: By reasonable allocation of SWAP space, the data processing process can be accelerated, especially when running large applications or games.

Improve stability: The existence of SWAP space can improve the stability and reliability of the system, because even if the memory is tight, the system can still maintain basic operations through SWAP space.

Note:

Although SWAP space is a very useful feature, users still need to be careful when setting SWAP in large hours. Swap space is too large or too small may have a negative impact on the device:

Excessive SWAP space: If you allocate too much SWAP space, it may cause waste of hard disk space because not all SWAP spaces will be actually used. In addition, too large SWAP files may also affect the read and write performance of the hard disk.

Too small SWAP space: If SWAP space is too small, the system may slow down or even collapse when the memory uses.

How to set the right SWAP space:

In order to ensure the best performance of the equipment, users should reasonably configure the SWAP space according to the actual memory capacity and expected load of the equipment. Generally speaking, the size of the SWAP space can be set to 1 to twice the physical memory, but for modern equipment with large memory capacity, you can consider setting a smaller SWAP space, because the current memory management system can usually be effectively managed by effectively managing it. Large physical memory.

Observe equipment information:

Before setting SWAP space, it is recommended to observe the memory usage of the device, including the memory consumption of the application, the common memory peak, etc.

This can help determine a reasonable SWAP size, which can respond to memory demand in most cases, but not waste resources.

in conclusion

Correct configuration SWAP space can significantly improve the performance and stability of the device, especially when processing large applications or games. However, users need to adjust according to the specific situation of their own equipment to avoid problems caused by improper SWAP settings. If you need further help to determine the appropriate SWAP size, or more information about how to manage and optimize the SWAP space, please ask at any time.
