says who?

if you have running applications than for a reason
swap them out for cache POSSIBLY re-needed disk blocks
will cause delays and re-read from disk

on a typical workload with 8-16 GB RAm there is no sible reason
for swap, especially on workstations but mostly also on
servers if they have enough RAM

and i am speaking here about a server hosting some hundret domains
as example which has 7000 mysql tables, no single byte swapped
and a load-avg around 0.8

again: swap may be usefull if you have too few RAM
on modern machines starting with 8-16 GB this is esotheric
