Applied v6 and re-run the tests. 
Functional test passes ok on my boxes.
Pert-tests numbers below.
As I can see pretty much same pattern as in v5 remains:
MP/MC on 2 different cores and SP/SC single enq/deq
show lower numbers for _elem_.
For others _elem_ numbers are about the same or higher.
Personally, I am ok to go ahead with these changes.
