Hi, I’ve been using W3TC on an older wordpress site for some time now mostly for managing page cache on disk & purging varnish when posts are update. Recently have been looking to reduce DB load by enabling the database cache and pointing it to a memcache instance and have been having issues. Everything looks OK, but when I load pages in wordpress I don’t see any connections initiated to the memcache instance unless I specifically load the W3TC plugin page under /wp-admin/ – I also see connections initiated to the memcache instance if I tell the plugin to flush the memcache cache, so it appears to know about the memcache instance & how to connect to it, but it does not appear to be using it in normal, non-admin operation. Thoughts?
