Public bug reported:

The floating IP translation rules generated by the l3 agent do not match
the format in which they are returned by iptables. This causes the
iptables diffing code to think they are different and replace every one
of them on an iptables apply call, which is very expensive.

See https://gist.github.com/busterswt/479e4e5484df7e91017da48b38fa5814
for an example diff.
