I have kubuntu 18.04
with 20 gigs ram. Does anyone know what the optimum
size swap area that I should have? Currently, my swap
partition is 2
gigs. Can I increase that by creating a swap file in
addition to the
swap partition?

Is swap size still as relevant as it was a decade ago?
On a host with 20G RAM, I'd imagine the likelihood of
hitting swap being much lower. Having a couple of G
available just in case seems like a good idea, but I'm
unsure if the old (Total RAM * 2)=swap equation still
rings true.

According to this article:
https://www.cyberciti.biz/tips/linux-swap-space.html
RedHat basically says that for CentOS server 7, a minimum
of 4G is recommended. The caveat to this is that if your
system needs to hibernate/suspend-to-disk, in which case
you'll want 1.5-2x RAM as swap in order to write in-use
memory to disk.
