In realistic practical terms anything that involves customer's money is
IMO BAD on a home grown FS solution (I'd rather use Oracle or something)

OTOH a hit counters (and other type of counters) IMO is better at the FS
level. Storing it in an RDBMS implies an extra
no_hits_per_day_to_the_web_site going to the RDBMS. Also in many cases it
is not that important if some hits are 'lost' in which case you can write
very efficient code with minimal locking.

With file systems like RaiserFS or XFS it is be possible to have huge
amounts of small objects in each directory (and still be efficient) and
also provide journaling support (Seems to me they are essentially DBMS).
It is possible (but probably difficult to implement) to have a RaiserFS
Storage backend to ZODB. A better fit than an RDBMS backend because
then you can take advantage of all the powerful FS tools like quota
control, selective backups etc etc.
