You know, I don't know the answer to that.  I would guess that it's the
default compilation options, so if you say that it uses that by default,
I'll believe you.  I tried grepping the binary but didn't find anything
that indicated type of structure.

I found this in namei.c.  Dunno if it helps:
 *  Directory entry file type support and forward compatibility hooks
 *      for B-tree directories by Theodore Ts'o (tytso@mit.edu), 1998

To me that doesn't really tell anything though.

Anyway, I fired off an instance of my test program that created 3
million files and it finished in about 26 minutes.  But then I found
that I had filled the partition so I shortened the file size a little
and restarted it.  It was running when I left and I'll analyze the logs
tomorrow.  BTW, that was on a machine with 5400 RPM 40 GB HD and 128
Megs of RAM (trying to starve the system for resources to get rid of
effects of caching and buffering).
