"High water" Memory fragmentation still a thing?

Now this is a question for the computer scientists. The problem is quite
amenable to purely mathematical/statistical treatment. No doubt they've
been at it for decades.

My personal hunch is that GC in general works best with an ample amount
of RAM, where "ample" means, say, ten times the minimum amount needed.
As a bonus, I'm guessing the ample room would also all but remove the
memory fragmentation issue.
