CMSize allows you to view size information about the content store.
CMSize consists of two panels:
Object Size
This panel allows you to determine how many instances of a specified group of classes are under a specific
scope as well as how much space (approximately) they are taking up in the Content Store..
Object Count
This panel allows you to determine how many instances of each objectClass there are in the content store.
When using CMSize you will be warned that the query to CM is CPU and database intensive, please bear this in mind when using this tool.
