Mark,
thanks for update.
I've Just made a brief try.
Performance is much better now but numbers I can see with my old branch
are still unreachable.
Approx х2 times slower ( it was ~10х slower before) for random 4K r/w
using FIO against standalone bluestore instance.
Thanks,
Igor

appears to resolve the performance regression in my tests:
