Subfile performance question

A coworker stated the other day that handling the page-up and page-down of a subfile in the RPG program was more efficient than letting the system handle the scrolling. They couldn't give an specific reason just that 'that's what I have always been told'. It was news to me and I'm having a hard time seeing how that would be true.

Does anyone have an information or links to information about the scrolling efficiency of a subfile vs. scrolling in the RPG program? I may write a couple of test programs to do some timings but thought I would ask first. I don't write a lot of subfiles these days and writing them would not be a simple task as my subfile skills are rusty.
