Hi All,
I've got one complex page which loads slowly, load times being:
FULL "node-rest-body.tpl.php" file
Authenticated User: 20.2 sec., 19.5 sec. (first run, second run)
Anon User: 5.4, <1
EMPTY "node-rest-body.tpl.php" file
Authenticated User: 19.4, 19.0
Anon User: 5.3, <1
All my other pages load within a second. I had been concerned my custom php file might be contributing to this as it does a lot of background wizardry prior to displaying page contents, but as you can see, by me making that file negligible "print 'hello';" total load times were cut down by less than a second, meaning 95% of the time is spent with Drupal php churning through the page code.
I also ran the page through Webpagetest several times and found that the Time to First Byte is about 5-6 seconds, with the page first displaying at about 9-10 seconds, a separate issue I am trying to address.
This page is composed of about 200 cck text fields, but otherwise it is not remarkable.
