====== Memory Footprint Reduction ======

These are some notes I made on reducing DokuWiki's memory footprint while investigating issues described in the mailing list, "[[http://www.freelists.org/archives/dokuwiki/03-2008/msg00087.html|memory size error]] and on the forum, [[http://forum.dokuwiki.org/thread/1740|Large pages not parsed]]

I'm making them here to keep a record.  At this time none of these are being worked on, so feel free to take a look come up with an improvement

  * Don't load replacement utf-8 functions if not required.
  * Investigate why loading of cached instructions boosts memory usage so much.  In a "?purge=1" scenario, the instructions have already been created and freed, yet loading them from cache for xhtml parsing increases memory usage far above the figure during their previous use (metadata parsing).
  * Investigate streaming instructions rather than holding the whole lot in memory
