Is there a method that returns every page? Staticpublisher example seem to point to SiteTree::get(); but on my site (c. 2500 pages) when I run it it maxs out CPU for a while and doesn't generate any cached versions of pages.

Do you know what part is causing the delay - the fetch of pages or the actual processing of each page? If it's a fetch, then no nice way apart from querying for the page links in batches.
