I just sent a patch that makes viewing the revisions list for a
DokuWiki page much faster. The changelog system still needs to be
rewritten, but this should make it better in the meantime.
The main problem is that all the changelog items are stored in one
monolithic file. This file gets loaded into memory (and split into
lines) by PHP, at least once every page access. As 'changes.log' grows
without bound I suspect it will eventually clobber PHP.
The approach I would suggest is to keep one changelog file for each
wiki page. These files could be kept under the 'data/meta/' directory
as '<id>.changes'. There also needs to be a function for quickly
loading the last line without reading the whole file into memory. The
global changes file could be kept as 'data/meta/_dokuwiki.changes',
however it should only store enough changes to quickly render the RSS
feed and 'Recent Changes' page.
