2020-10-26 : MaxRamPercentage is not what I wished for
<em>This entry has been marinating for most of the year 2020. I should have published<br>this opinion way earlier maybe end of 2019, but it took me time to realise I should split<br>a bigger piece in smaller articles that hopefully made sense on their own.</em><br>
