Docker swarm overlay and a big load softirq?

Hello.

Continue to expand the service of one of the websites in Docker cluster. At the moment, faced with the problem. What CPU in softirq increased to 40%. Tested on nginx. Network downloaded to 200 megabits approximately. Roughly nginx hangs on a separate piece of iron, next after him, on other piece of iron is already running php. Well, is it normal for this situation and what to do if the network load will increase in 2 times? How then can this at least on the processors spread?
Without the usual nginx Docker created a load 3 times less... So that power iron there is enough and not afraid if a couple of kernels will go to the processing network...
