I thought this was interesting enough to share with everyone.

tl;dr: give Firefox Quantum a try!

We're doing UI memory leak testing of webadmin across browsers. The tests
use selenium [http://www.seleniumhq.org/] which drives the browser to do
hundreds of repetitive actions, which then over time exposes browser memory
leaks in the actions being performed.

X = repetitions (over time)
Y = memory consumed in MB

The graph shows that, as the number of repetitions through the application
increases, Firefox Quantum 57 leaks less (lower slope) than Chrome 62
(latest) and older Firefox 52 ESR. Also, it uses less memory the entire
time (lower on the graph). [FF 57 is also just plain faster per repetition,
but I haven't posted that graph here. Take my word for it :)]


Nice, especially that it is both faster AND takes less memory (otherwise
you could have blamed a GC strategy favoring speed over memory
consumption).

Worth blogging on ovirt.org.
Y.
