Ok, that's really nice - and this approach has no arbitrary limits/tunings in
it.
Do you have a performance comparison to your first series (patches 1+2+3 IIRC)
-
how does this new series with MCS locking compare to the best previous result
from
that old series? Do we now achieve that level of performance?
Thanks,
