For memory consumption, I don't know why phpBB3 can use such large memory in a single session, around 3~4 MB, and sometimes hits 5~6 MB in submitting posts. It's not so bad comparing with vBB, but I do know some forum softwares can limit the memory consumption into 800 KB in most of the pages with rich features and amazing response speed. Have you ever tried Discuz!?
This is important for some hosting service provider, they will tend to persuade user using a light load forum.
If not being binded in so many hosting machines, phpBB2 wouldn't be the most widely used forum software. If all you want phpBB3 to be the first choice of all forum software, you need optimize it.
The memory distribution in index page:
