*BOGGLE*

I could see a justification in saying "aim for 400MB, because then
unexpected spikes won't kill you", or "aim for 400MB to ensure that
you can run multiple instances of the app for load balancing", or "aim
for 400MB because you don't want to crowd out the database and the
disk cache", but not "aim for 400MB because the garbage collector is
only 10% efficient". Get yourself a better garbage collector. Employ
Veolia or something.
