I think unless such benchmarking is done in the next 24h we need to move
this patch to the next CF...

Thank you for your comments.
I didn't x86 benchmarking.  I even didn't manage to reproduce previous results on Power8.
Presumably, it's because previous benchmarks were done on bare metal, while now I have to some kind of virtual machine on IBM E880 where I can't reproduce any win of Power8 LWLock optimization.  But probably there is another reason.
Thus, I'm moving this patch to the next CF.

I see it's already moved. OK!
