Francesco Mari commented on OAK-4105:
-------------------------------------

[~mduerig], [~dulceanu], given the 10% discrepancy between the approximate and real size of
the repository, I agree on revisiting the current approach.

> {{FileStore.size()}} is prone to lock contention and should not be called too often.
As OAK-2879 already introduced an approach for tracking the current size of the file store
without having to lock, we might as well promote his to be "the official" implementation.
