When comparing the memory occupation numbers in the Chromium task
manager with the output of the "top" command, all numbers in "top" are
larger than in the task manager, especially the main task takes several
times the task-manager-reported memory in "top".
The CPU consumption of the main task is going up with the time. It is
between 30 % and 50 % now. The CPU consumption of the tab and add-on
tasks is negligible.

Severe memory leak: 13 GB RAM in 3-4 hours
Status in chromium-browser package in Ubuntu:
I am on Bionic with a new Lenovo X1 Yoga (2nd gen., current model)
with 16 GB RAM.
For some weeks now chromium-browser has a severe memory leak. It fills
up 13 GB of the 16 GB RAM in 3-4 hours, independent how frequently I
use the browser in this time.
I use many tabs (~20-30) and as add-ons I use Adblock Plus, Ulmon
CityMaps2Go, and Google Dictionary. Next time Chromium blows up I will
remove one of them to find out if an add-on is the culprit.
When Chromium fills up the memory sometimes the computer gets simply
slow, sometimes the rendering engine goes away (all tabs are simply
solid grey instead of shown their web page), and/or there are pop-up
windows about add-ons having crashed.
To get rid of the blown-up Chromium I run "top" in a terminal window,
sort by memory occupation (Shift + M) and kill the process making the
first place in the list (K, then 2 times Enter). This blown-up process
is always the master process of Chromium, not one of the tabs, as
killing this process pulls down Chromium completely (and frees the
