Increased latency after update


(Eadbox) #1

After I updated to Docker 1.11.1cs1 my response times increased by a lot, both the final response time as well as the latency between my containers.

The second red bar is the update.

If I ping from one container to another the latency is way higher than expected for internal communications and with a very high jitter too.

Any idea what could it be?
