This looks really promising! Gonna try it out on a couple of sites.<p>Wonder how it'll behave in the worst case scenario where:<p>1. WP cache is cleared<p>2. Someone initiates a complete crawl of the site (for SEO or whatever reasons)<p>This would usually put a heavy load on the server. Wonder if APO would help and keep serving the old cached pages, or if it would try to rebuild the cache itself, thus adding to the problem.
