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.
