Just testing latest Manjaro KDE plasma desktop in Virtualbox, I was pleasantly surprised at how fast it booted (really, really fast) and how low it's RAM usage was.
Take a look:
Like: OK, 476Mb RAM usage isn't at all bad and Plasma is really a very nice intuitive desktop.
Then Elive 3.8.16 Beta:
Like only half the RAM usage ......
Albeit that startup was almost twice as long. That's something that might warrant a good scrutiny.
And then to top stuff up, Deepin Linux live version.....which booted very fast as well.
I like Deepin lately but the live version is on a parallel with Elive Stable 3.0 i.e only a notch higher with Debian 8.0 so hardly comparible to the other 2.
The installable version is Buster based with a Plasma desktop but alas no live version yet.
All in all it has some interesting GUI choices which we certainly should take note of.
Give it a virtual try if you've got time. :+1
The PinebookPro arm64 laptop with Manjaro Plasma desktop shows the same RAM usage .... so there's definitely something Elive could offer there ... as in not wasting resources.
High time I started looking into that again (note to self, actually)
And this is mem usage on my installed machine:
