One is a flat text file export of the database (.ldif)
The other is a set of binary data based off of the flat text file export,
but includes things such as indices. You cannot correlate the two size
wise.
If your binary database after an import with slapadd -q is ~11GB, than
that's the "real" size of your database.
How much memory do you have on the system you're using?
I would note that it is not advised to use XFS with back-mdb.
