This is definitely not a common thing. I have never had more than one
profile. Then again, I have only worked for one company at a time,
never 6 at the same time. Don't you also have something crazy like 4
monitors at the same time?

While I don't do that, I find I need to do that every week or so. I
have noticed that on OS X firefox, any animated GIF displayed in the
active tab causes CPU usage to skyrocket and the fan to start blowing.
Guess how many cow-orkers constantly post animated emojis in the work
Slack instance?

A VM by nature can't share any of the RAM its guest OS is running, so
it's worse than usual.

As a counterpoint, kate with 10 files open has an RSS of 132M. Having
36 files open in an editor seems a bit crazy to me as well, but I
usually have 3 to 6 files open in vim, and vim like most text editors
loads the entire file into memory. 36 files that are all 86M or so
would easily account for 3G. Text files that are written by people are
almost never that large, but log files....

That seems the most likely scenario.

If that writeup is from 2012, it's at least 6 years out of date.

2015-vintage machine, 8G. I started KDE on Oct. 20, and top says 3912
M used. Most of this is firefox, not KDE, though. Maybe this is a
distro thing? Gentoo is somewhat more conservative than most distros
when it comes to versions and features. Also I've turned baloo off. I
don't need "file indexing", I can use grep -r like a normal person. :-P

AMD FX 3.8 GHz 4-core, 8G, no special handling of firefox. However, I
only have one browser profile and generally only one browser window, no
VMs running, only 1 monitor, and rarely use LibreOffice. Current GUI
things are 1 Barrier, 2 Dolphin windows, 2 Gwenview windows, 1 konsole,
1 kcalc, 1 GNUcash, 1 Gimp, 1 System Settings, 1 Firefox window with 13
tabs, and the general KDE stuff that runs in the background. Note that
YMMV.
