Probably PM's caching beats this hands down, but I've found that if I
do my pagelist with full selection criteria and save off just the
NAMES of the pages in a comma-separated list (as PowerTools does by
default) and then use that list for subsequent pagelists it saves a
bunch of time.  I'd be curious if anybody is actually doing benchmarks
what the actual comparison is:
   1. doing it 3 times without caching
   2. doing it 3 times with caching
   3. doing it using the name method as I'm doing

REQUIRES: WikiSh (no read or write access required), PowerTools

{(wikish set -s pagelist = "`pagelist wrap=inline group=PmWiki`")}
(:cellnr:)Sorted by creation time (most recent first)
(:cell:)Sorted by modification time (most recent first)
(:cell:)Sorted alphabetically
(:cellnr:)(:pagelist name=${pagelist}  fmt=#bygroup order=-ctime :)
(:cell:)(:pagelist   name=${pagelist}  fmt=#bygroup order=-time :)
(:cell:)(:pagelist   name=${pagelist}  fmt=#bygroup  :)

I used group=PmWIki as my selection criteria because I don't have a
bunch of pages with an obsolete PTV.  Obviously a name-based selection
like that isn't going to see much difference from the "caching", but
hopefully when it involves PTV access you would see a significant
