Just a note: At least Unix systems (but I'm pretty sure the same is true
for Windows) do cache frequently accessed filesystem data in memory...
so you haven't that much disk activity for read only accesses. In fact
it would be possible to install DokuWiki on a RAM disk... Just as note -
you're right about the DB advantages of course.

However as much as I like to talk about what could be done we have to
concentrate on what can be done with available ressources (think:
skilled programmers with enough time). If anyone needs a database
backended Wiki: there are plenty available. DokuWiki is not meant as a
competitor for mediawiki.

So talking about databases is out of scope for me. Top thing on my list
is to get out the new release. Of course I'd be happy to get as much
performance patches as possible for the following release.
