This is of course desirable. 4k is the page size on x86, which makes the
unified cache in 2.3 (2.4) much faster on such fss. I just yesterday
converted all my fss to 4k block size. /var grew from 84M to 91M.
Also in 2.2.x 4k fss are significantly faster when it comes to deleting
(or truncating) large files or big directories, because you need fewer
blocks for a given file size and therefore increase the threshold for
introduction of {,double,triple?} indirect blocks.
