That's true for data, but not for code. That's also an unusual apache configuration. I've never known anyone that didn't start just one, and let it start the others, at least since they added virtual server support. At this point, I don't know enough about shared libraries on FBSD. Is the data segment shared COW amongst all the processes that are using it, or does each process get one of it's own?
