Object metadata varies greatly depending on a few factors like versioning, overwrites/updates, object size, etc. The best way to calculate this today is to create a million objects and then divide the metadata space in ECS by the object count. When we do this without any user metadata, we come up with a figure around 6kB per object. Since metadata is currently stored as 3 replicas, this means about 18kB on disk. This is an area we're currently working hard on and we expect significant improvement in the next few releases.
