dude i am so tired of not having enough technical info to make informed decisions about the applications i use

suppose you are trying to find an optimal way to use discord. i have read once that discord integrates a decent bit of optimized native code, but i can't find any info about this on reddit!

so suppose then i just want to compare RAM usage. i take the size of resident memory of Discord from HTOP, open up the firefox process manager, only to be greeted with a singular Memory column with X MB for each subprocess. but there is not a single page on the internet (that google is surfacing) that explains how to interpret what these numbers represent
