I think you might be a bit confused now this all works. Docker by default uses bridged networking, which by default spins up a little crappy docker-proxy process for every port. You can disable docker-proxy and instead use hairpin routing mode if you have a modern kernel. However, I'm almost certain that any task you run via docker on mesos default to host networking. Docker, LXC, mesos containers all use the Linux kernel network namespace + perhaps some iptables/libnl magic for the networking bits. Docker in host networking mode will do networking at mostly native speed. I suggest you run iperf on mesos in the various configurations. It should be pretty straightforward to test the overhead, but I suspect docker + host networking will more than work. Give it a go and let us know!
