> On large directory structures it takes significant time to iterate through the file and directory counts recursively to get a complete ContentSummary.
> When you want to just check for the quota on a higher level directory it would be good to have an option to skip the file and directory counts.
> Moreover, currently one can only check the quota if you have access to all the directories underneath. For example, if I have a large home directory under /user/joep and I host some files for another user in a sub-directory, the moment they create an unreadable sub-directory under my home I can no longer check what my quota is. Understood that I cannot check the current file counts unless I can iterate through all the usage, but for administrative purposes it is nice to be able to get the current quota setting on a directory without the need to iterate through and run into permission issues on sub-directories.
