Please explain exactly how the non-container network namespace test was
set up, though.

I don't know what this is, linux isn't at 3.20 yet :)

Did you use the same kernel for both?

lxcbr0 is a NAT'd bridge so you'll have slowdown due to that.
You might try specifying the same bridge you used for the netns
tests.  That would explain a difference in performance.
