Efficient but wrong unless you can guarantee file names won't
contain newline characters.

Portably:

find .//. | grep -c //

GNUly:

find . -printf . | wc -c

Note that it counts ".", but none of the "." or ".." entries in
any of the directories.

But I think the OP was looking for a report a la du to get a
summary of the number of files per directory (which you can then
pipe to xdu/xdiskusage for instance to get a graphical
representation).
