If you use the Docker default bridge network stack, I have heard of performance impact up to 30% (depending on workload / kernel version / etc) We use "host" networking which moderately reduces security but all but eliminates the performance impact on the network. You should make sure to do tests that this is true in your environment but I believe it is possible to get near native performance if you are willing to test things thoroughly and report issues as they arise.
