Not only memory, but loading time. The php include_once() that is used to
load modules is an expensive operatin.

Both can be remedied (to a large degree) by using an op-code cache that
caches in memory (such as what APC does by default, others require certain
config options).

There is an article on 2bits coming up soon on details. Stay tuned.
