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?
