This may be where that came from:

Here's a simple look at RAM before and after first launching IceWM, then
rebooting, then a freshly installed Plasma session on an old single core PC that
had had only KDE3 and IceWM on TW.

I rebooted before launching Plasma and Konsole on the same PC:

No, it's not Debian. I never put Plasma on my Debians, which all use TDE. This was
a freshly updated Tumbleweed, so the Plasma version is fresh. There's no XFCE on
it. It won't be added either, as there's nothing about it I like better than KDE3,
TDE or Plasma, and the disk has no room for more additions, worthwhile or
otherwise. Thus, the difference between XFCE and Plasma or IceWM will need a
different PC.

The point is, Plasma can be rather lean, using only 116260 more than IceWM to get
a basic session started.
