iptables-restore is using one atomic transaction to replace one whole
table. 

iptables when changing a single rule is using one atomic transaction to replace
the whole table as well.

So I doubt there was much difference between the two of them.

However, if you want to change 100 rules, using iptables is 100 times the
overhead as iptables-restore.
