Thanks for the information. Currently we are mid way to our production
with the scavenge before remark option enabled. I try my best to add
CMS statistics to the list of changes.
As a separate action we will try to increase the max abortable
preclean time from 5 to 11-12 seconds.
I will update you as soon as we have the data.
