Wow.  You have more directories than regular files!  Given that there
are no hard links, that implies that you have at least 2,079,271
directories which are ***empty***.

The inline data feature (which is still in testing and isn't something
I can recommend for production use yet) is probably the best hope for
you.  But probably the best thing you can do is to harrague your
developers to ask what the heck they are doing....
