Sizing Swap Space:
------------------
The amount of swap space to allocate depends on the amount of RAM installed on the machine. The following conditions show the RAM size followed by the reasonable swap space size, respectively:
<= 2 GB: 150% of the RAM size
Between 2 GB and 8 GB: Equal to the RAM size
> 8 GB: 75% of the RAM size
Some examples are shown in the slide. You can use the free command to see the size of the swap space, and also to see how much of it is being used. You can also view the contents of /proc/swaps.
Note: Diagram sizes are not to scale.
1GB RAM = 1.5 GB swap
4 GB RAM = 4 GB swap
10 GB RAM = 7.5 GB swap
