if whatever you are running on said machine is going to be useless if you are swapping you don't need much swap. The apps I deal with if we get much into swap has severe performance issues and is basically in an outage.
I have 72core/1TB ram and have 30GB of swap (pre zram os) The reality is if we are swapping then something/someone screwed up (too many process, process leak, memory leak, machine sized wrong).
