I recently had a similar problem on my server which is running
different wiki software. So I went to
http://www.pmwiki.org/wiki/Test/Test and got apparent page build times
of 3+ seconds. Seemed excessive. But I may be reading the times at the
bottom wrong. Anyway, I'm guessing Pm's server doesn't have CPU
limits, like a shared hoster.
The only way to test the software fairly, is to install a couple
systems (like drupal, moodle, etc) on the same machine, and get them
to do some kind of comparable task. But even that's not really fair as
wiki's do so much more processing, and something like PmWiki has so
many more capabilities. So I'm not sure what the best solution is.
But I would like a bit more discussion of the issue--to see if there
aren't ways to test for a problem, tweak performance, or perhaps a
recommendation of where to get good webhosting that won't cause this
