Hi guys I’m back after a short ban so thought I would take another look at this controversial topic. I am pleased that you have been so busy and must thank whoever for more evidence to back my case - I can’t believe for one moment that no one else hasn’t noticed this official it’sFOSS review of heavy use of resource standing still.
I must also thank @kovacslt for his videos even though I can’t understand the purpose. We see at the end of the PCLOS video; the cpu’s workload climbing, maxing out at 100% a sure sign of impending doom rendering the OS unusable. 
If we then look at the Trisquel video we see just the opposite with the cpu’s workload continuing to fall to around 7% as expected from a good OS and confirms my own cpu experience. 
This has of course been entirely covered by the professional tester at DistroWatch - Quote “The distribution ran unusually well in VirtualBox. The MATE desktop was highly responsive, new applications opened quickly, and the operating system ran smoothly.” Plus - “When I switched over to testing the distribution on my workstation the performance was again great. I love how responsive MATE was in both test environments. The desktop flies on this distribution and windows are wonderfully snappy. MATE is a mid-weight desktop environment, yet it performs like a lightweight window manager on this distribution.”
Exactly what I find when I use the Full Monty version.
I do hope that the above has not come as too much of a shock…? To quote al-things-linux “and only 370 MB of RAM in use after a fresh boot, probably the lowest ever seen. A decent use of hardware leaving plenty to spare for actual operation.” Yo are they in for a shock - I must update them soon.
It comes from my LXDE Dell E6420 MiniMax-OS with all the usual expected of a Full Monty Distro - full suite of LibreOffice, Gimp, etc plus performance measuring and system reporting applications from its 20,000 app repository. 
Another it’sFOSS world record for efficiency - Enjoy
