What is swap space utilization?

What is Swap space? Swap space is a restricted amount of physical memory that is allocated for use by the operating system when available memory has been fully utilized. It is memory management that involves swapping sections of memory to and from physical storage.

What happens if swap space run out?

The consequences of running out of swap space affect a larger number of users on a big server, so it wise to allocate a lot more than you normally need to cope with any usage peaks.

It also means that you need to be sure you have the RAM to support this operation. An easy way to do this is to run ‘free -m’ to see what is being used in swap and in RAM.

How do I reduce swap usage?

In most cases, high swap usage may mean that the RAM has heavy load. You can reduce the swap usage by reducing the RAM usage or adding the swap usage.

Why is swap usage so high?

your swap usage is so high because at some point your computer was allocating too much memory so it had to start putting stuff from the memory into the swap space.

Does 32gb RAM need swap space?

If RAM is less than 1 GB, swap size should be at least the size of RAM and at most double the size of RAM. If RAM is more than 1 GB, swap size should be at least equal to the square root of the RAM size and at most double the size of RAM.
