[dokuwiki] Re: Load balancing hypothetical

Is it possible to load-balance a filesystem? And would it be possible to do so within the Dokuwiki architecture? I DO NOT want my page and media files in a database, save possibly by mirroring. 

Simplest approach might be to use one file system only for writes
rsync to other file systems which are read only, and serve pages. A 2
minute delay in rsyncing would probably not hurt. Sessions are another
story though and the biggest pain would be the breadcrumbs (would be
cool to move these purely clientside, using cookies and Javascript to
render them) - while they're server side, you have a lot of writes.

For actual load balancing, tools like Perlbal, Pybal
(http://svn.wikimedia.org/viewvc/mediawiki/trunk/pybal/) or Squid can
help, as reverse proxies.

Otherwise, it's a matter of researching distributed file systems -

point.
