The results for mainline 4.8.4 and 4.8.4-ck4 on a multithreaded hexcore (init 1) can be found here:
http://ck.kolivas.org/patches/muqss/Benchmarks/20161024/
and are copied below. I do not have swap on this machine so the "memload" was not performed. This is a 3.6GHz hexcore with 64GB ram and fast Intel SSDs so to show any difference on this is nice. To make it easier, I've highlighted it in colours similar to the throughput benchmarks I posted previously. Blue means within 1% of each other, red means significantly worse and green significantly better.

As you can see, the only times mainline is better, there is less than 1% difference between them which is within the margins for noise. MuQSS meets more deadlines, gives the benchmarked task more of its desired CPU and has substantially lower max latencies.
I'm reasonably confident that I've been able to maintain the interactivity people have come to expect from BFS in the transition to MuQSS now and have the data to support it above.
Enjoy!
