I'm slowly coming up the Drupal performance learning curve. APC and MySQL query cache were easy. autcache is a bit more challenging.
I'm trying to understand authcache. I turned it on, not bothering with memcache, and after I realized that you can't test it (easily?) with apachebench, started playing with it interactively. Seems to work great except that Authcache Debug says it's making ajax requests, and I can't figure out why. In the following example, I opened page node/251 (by its long name), then clicked on Authcache Debug to see what it said:
Authcache.info (logged in: joe)page_render: "1437.65 ms" page_queries: "366 queries @ 516.49 ms (36%)" cache_render: "2.07 ms (69,352% increase)" cache_uid: "2" cache_inc: "database" cache_time: 1389502279 node_author: "admin" (page_age): "17 seconds" Disable caching for this browser session HTML/JavaScript time: 99 ms ________________________________ Authcache.ajaxRequest #1 Request:q: "node/251" node_history: "251" Response:node_history: "1389502279" db_queries: "2 queries @ 55.2 ms"
Any clue as to how to figure out why it's making that ajax request?
Thanks, Dan
