The problem is evident. If you minimal allocation size is 512 bytes, per
file you waste 256bytes.

If your minimal allocation size is 4096 bytes, per file you waste 2048
bytes.

Mean values, of course.

This waste is per file. If you have a lot of small files...

PS: I guess ZNODES waste a lot of space too when using 4096 bytes sectors.
