In terms of 'normal', I tend to build my systems with equal swap and
memory, and then leave the overcommit ratio at the default. Still, I
think the best thing is to just keep tabs on how much memory has been
committed, how much is actually being used, how much swap you're using,
and what your commit limit is. You can then fine-tune things as needed.
