Hello. I never had more than 300 pages on a wiki, running the SQLite PageStore 
class. It will be interesting to test it with more pages, and there are some 
encouraging comments at the SQLite-Talk page about performance improvements, 
speed of searches, pagelists and includes. 

OTOH, recent tests on our new PmWiki.org server (with the default PageStore, 
not with SQLite) showed that in a huge pagelist or search -8000 pages-, most 
of the processing time was spent on ordering and formatting the results, like 
1000 times more than the time spent opening and reading the files. Unexpected.

I think for a large number of large pages, edited often by many people at the 
same time, and with many visitors, the performance will likely be worse than 
the default PmWiki engine on a recent filesystem (Reiser4, Ext4, JFS) and with 
per-group (sub-)sub-directories as Pm suggested.

The SQLite class needs testing. Most of my sites have been using the SQLite 
recipe for years, but they have few pages, editors and visitors.
