Authors (or else PmWiki) still need to be smart enough not to cache
read-protected pages or pages that are somehow "dynamic".

But if you want to try PmWiki's built-in caching (which already is
smart enough to know how long to cache pages, and to not cache pages
that depend on the visitor's identity or other timing items), then 
try the following in config.php:

    $PageCacheDir = 'cache.d';
    $EnableHTMLCache = 1;

It can also be done on a per-group or per-page basis in local
customization files.

For whatever it's worth, the pmwiki.org site gets ~800,000 views
per month with no caching.  (A "view" here is a request for a wiki
page; i.e., it's exclusive of requests for uploads, css files,
images, etc.)
