I have a number of mashup pages (actually, mostly custom posts; one is a page) on my WP site that load slowly given the number of feeds, slow API calls, etc. on the templates, and am hoping that this plugin can assist.
What I have discovered so far by testing W3 Total Cache on multiple browsers, however, is that the cache only seems to work after a page is loaded (even if "Automatically prime the page cache" is enabled...is this its intended functionality?), and doesn't seem persistent, i.e. when I revisit the site after an hour some of these pages need to be recached.
Currently have page cache set on 300 sec update interval, 20 pages per batch, Google XML Sitemaps installed with posts prioritized to ensure custom post mashup pages get attention.
I realize I'm a newbie to this great plugin, so help/advice welcome; thanks.
