I'm not very knowledgeable about Vi, I had someone else configure it for me as a pager a while ago. I used to use it (as a pager) to work with database dumps which were typically multiple Gigabytes big. It's obviously slow to do certain things, compared to smaller files, but that's to be expected as simply seeking through these files would take time. As for Emacs, I either use Hexl mode or I used to use a modified version of this: https://github.com/mbriggs/emacs-pager https://github.com/mbriggs/emacs-pager but cannot find a source at the moment. But, even if not used as a pager, Gigabyte file will work. That's still far from the breaking point. Not as snappy, and if you have a Python source file that's Gigabyte big you will have to disable Python mode, for example. But with logs / database dumps that's usually not a problem.
