If things have got worse with stable/buster, is it possible that you
use xpdf to browse sizeable documents?

I find 4GB very adequate for browsing with lots of tabs etc, but
reading PDFs (like many people, I've been reading some large reports
and court filings over the last year or two) on buster can bring the
computer to its knees quite rapidly. When I switch back to Firefox,
fvwm displays its window, but Firefox can take half a minute or more
just to rerender itself.

The bugs concerned are

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=942086
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=945188

As my workaround, I've modified mc's mc.ext file to open PDFs
with xpdf when I press Return, but with zathura when I press F3.
(But I miss my customisations of xpdf with the latter.)

Swap growth is a clear symptom of the above if it's happening.

Personally, I've never bothered; I rely on the performance
I experience while doing my habitual tasks. But that's partly
because I don't have an easy way to remedy matters.
