I'm quite surprised by what you say.

My mailman3 instances takes 50MB RSS RAM (it's running since june the 2nd)
list     15305  0.0  0.3 172120 50232 ?        Ss   juin02   0:01 /usr/bin/python3 /usr/lib/mailman3/bin/master -C /etc/mailman3/mailman.cfg

The web part takes 76MB RSS RAM.
www-data  5082  0.0  0.4 506556 76776 ?        Sl   juin02   0:01 /usr/bin/uwsgi --ini /etc/mailman3/uwsgi.ini

I have no clue of what could explain such a consumption in your case.

I'm really open to find solutions as soon as we identify the issue.

Cheers!

It's far easier to fight for one's principles than to live up to them.
