It depends of course on what *else* you are running, but prima facie,
swapping doesn't look to be the problem. Nevertheless, is a disk going
wild while you are opening the file?

This is the wrong process: this is the line for the "grep emacs"

But is it org mode that runs like this? or something else? The elp stats
showed that org-mode was pretty much in the noise.
