the variable is populated (i.e. DNS lookup is done) for every message, even
if you don't use fromhost in any of your templates.

arguably this is an optimization that could be made, but it's usually
easier to just allow people to disable the DNS lookups globally (adding the
-x option to the rsyslog command line)

using it in a template will not slow things down, the damage is already
done.
