   * https://​www.linux.com/​news/​all-about-linux-swap-space Swapping is necessary for two important reasons. First, when the system requires more memory than is physically available, the kernel swaps out less used pages and gives memory to the current application (process) that needs the memory immediately. Second, a significant number of the pages used by an application during its startup phase may only be used for initialization and then never used again. The system can swap out those pages and free the memory for other applications or even for the disk cache.   * https://​www.linux.com/​news/​all-about-linux-swap-space Swapping is necessary for two important reasons.

A significant number of the pages referenced by a process early in its life may only be used for initialisation and then never used again. It is better to swap out those pages and create more disk buffers than leave them resident and unused.+  * https://​www.kernel.org/​doc/​gorman/​html/​understand/​understand014.html The casual ​reader ​may think that with a sufficient amount of memory, swap is unnecessary.
