A simple include should be faster than a PTV, and you can speed up your page 
if you have less includes. That means, your data is split into a smaller 
total number of wiki pages. 

See also the $PageListCacheDir variable that allows you to cache the result of 
pagelists and speed up the processing.


All pagelist cache is removed if any wiki page changes, so if your wiki is 
very often edited, this may not be faster (on pmwiki.org it is disabled for 
the same reason), but for sites that have many visits between edits it is 

Also note that a pageist is fastest with a trail of pages (even no need to 
cache it). It is in the form (:pagelist trail=Group.ListOfPages 
fmt=#include:) . See
