Swap memory for Beaglebone

General Discussion

I am using BeagleBone black board and running few applications in it.

I got this on using “top” command.

Should I be worried about 27.4 MiB free memory and allocate some swap memory for the device?

So far no “oom” issues based on logs. Is it safe to continue with this?

Probably not. 276M are used by buffering and caching, which can be freed up if needed, but won’t be unless you are running short of RAM, as it might be needed in the future.

Any decent operating system will make full use of all RAM where possible.

But it will depend on what stuff you are running and how much RAM those programs need. I wouldn’t try running a web browser for instance. Swap would be horrendously slow and best avoided.
