No. All of the data in the opening email are from 2.6.39. Each kernel
(2.6.39, 3.8 and 3.18) has a different performance problem. I will look
at 3.18 in depth soon, but from what I can see the fundamental concepts
of the load balancing have not changed (e.g., my tracepoints from 2.6.39
still apply to 3.18).
