How does the directory *itself* have a size of 2.8 megs?


If you write a large number of directory entries in a directory, the directory will grow in order to provide storage for those directory entries. You can imagine a directory as a text file containing all of the file names in the directory, with references to the location of those files, if that helps you understand why the directory itself will grow.

on many modern file systems, larger directories are stored as some sort of B-Tree or hash tree, so there's quite a lot of indexing data in there along with the actual directory entries.
