I've managed RBD cluster that had all of the RBDs configured to 1M objects
and filled up the cluster to 75% full with 4TB drives. Other than the
collection splitting (subfolder splitting as I've called it before) we
didn't have any problems with object counts.

These limits unfortunately aren’t very well understood or studied right
now. The biggest slowdown I’m aware of is that when using FileStore you see
an impact as it starts to create more folders internally (this is the
“collection splitting”) and require more cached metadata to do fast lookups.
Hi,
Are there any recommendations on what is the limit when osd performance
start to decline because of large number of objects? Or perhaps a procedure
on how to find this number (luminous)? My understanding is that the
recommended object size is 10-100 MB, but is there any performance hit due
