Two commands to create swap partition
The swap partition is used to hold the contents of physical memory (RAM) when it fills up. When RAM is exhausted, Linux will move inactive pages in memory to swap space, thereby freeing up memory for system use. Nonetheless, swap space should not be considered a substitute for physical memory. In most cases, it is recommended that the size of swap memory be 1 to 2 times the size of physical memory. In other words, if you have 8GB of memory, the swap space size should be between 8-16GB. If there is no swap partition configured in the system, when the memory is exhausted, the system may kill running processes/applications, causing the system to crash. In this article, we will learn how to add a swap partition to a Linux system. We have two methods: use the fdisk command

They are not as flexible as specialized tools, but they are readily available and require no special learning. CPU The following command will create CPU load by compressing random data and sending the result to /dev/null: cat /dev/urandom|gzip-9>/dev/null If you want a larger load, or the system has With multiple cores, you only need to compress and decompress the data, like this: c
