Requirements and a curious fact I noticed

I had to format and made a clean instalation on my laptop. (specs below). I tried Zorin Litle 16.1 which I like a lot and noticed that USBlive consumed 1.3 gb memory ram (Without any other program opened). I couldn't believe it. But I know distros behaviour could be different in each computer.
Then I checked with LinuxMint 19.3 USBlive, it only consumed 470 Mb Ram (more or less).
I would like to learn how this could be , has the Dock panel something to do?

How much RAM is being consumed at any given moment can vary a lot, depending on what processes are running in the background. For thoroughness in testing, I learned the hard way when distro hopping to try the LiveUSB of each distro multiple times in order to gauge RAM.

Ahh RAM. If I paid for 32gb's of RAM you best bet imma use all 32GB's of ram.

It's there to be used. Once it's being capped is when you gotta start asking questions.

Should I get more ram? The answer is yes, always yes
