--parallel avoids forking and startup costs of multiple curl
instances, and it avoids context switches and larger cache & RAM requirements
due to switching processes. It also allows reusing network connections and all
the associated connect costs. So, it should be considerably more efficient, but
you can probably saturate your network either way.
