Swappinessis a Linux kernel parameter that specifies how much (and how often) your system swaps data out of RAM to the swap space. The default value for this parameter is“60”and it can use anything from“0”to“100”. The higher the value, the higher the usage of swap space by Kern...
The swap gets used once the physical memory is used up. The swap disk is much slower than RAM, meaning performances can go down, and thrashing can occur. However, as long as you have enough RAM, having a swap area of any size won’t hurt performance at all. Releted Article [Red Fla...

Telling the system not to rely on the swap much will generally make your system faster. Values that are closer to 100 will try to put more data into swap in an effort to keep more RAM space free. Depending on your applications’ memory profile or what you are using your server for, ...
Swap space is a last resort when the physical RAM is fully utilized. The operating system moves less frequently used data from RAM to the swap space to free up memory for currently active tasks. How Does Swap Space Work? Swap space works by utilizing a part of the hard drive to temporari...
A big portion of the pages used during the startup of a program may see very little usage. Swapping those pages can free up more memory for other apps. If no swap space is assigned, if the RAM space is fully occupied, it can cause the system to crash, especially the systems with low...
