That usually, apart from command list length limitations,
happens because so many Ceph storage backends have too low
committed IOPS (write, but not just) for mass metadata (and
equivalently small data) operations, never mind for running them
in parallel with the user workload. They are very expensive, and
many Ceph storage backend are built to minimize cost-per-TB
only.
