Description

The diff_iterate API (which is used for many rbd CLI tools) operates on each block serially. Performance could be improved if multiple list_snaps operations were issued to the OSDs in parallel. This should increase performance in cases where the new fast-diff feature isn't available or in cases where precise diff extents are desired.
