On Linux at least, neither actually hits the network.  So this would
have to be an unusually small service for it to make any significant
difference.  Key-value lookups on data known to be in RAM, maybe,
like memcached or a local DNS server.  Even for those, optimizing
this factor would be near the bottom of my to-do list.  :)
