There are two articles on the ez.no setup:
1. http://ez.no/community/articles/clustering_ez_publish 2. http://ez.no/community/news/ez_publish_3_enterprise_setup_test (slightly outdated)
On decent hardware, I usually manage to get the loading time for a content page down to < 0.1 sec (0.07 or 0.08 after one or two refresh).
What I notice in your post is that you still have more than 20 SQL queries executed on the page. Using cache blocks you can get it down to 1 or 2. Then we can start talking business :-)
(I don't think you can go way below 0.1 on good hardware)
