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?

Does this happen when you open *any* large file or only when you open
the org file (and iirc, it was not a very big file: smaller than 1Mb?)

This is the wrong process: this is the line for the "grep emacs"
command, not for emacs itself. Maybe try "grep Emacs"? I don't know
what the emacs command name is on OSX.

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.
