I use
Google Analytics for my DokuWiki stats. Relies on Javascript just like koko's stats.
Another option is to use the
View Counter by Erazor. It is sort of a hack, but with the new action-plugins in DokuWiki 2006-11-06, it should be possible to incorporate in a plugin and save the counter data in the metadata for each page. Would require someone to write it into a plugin first though :-D
