I actually missed what happened here, maybe for the better.
Although certainly not everything is wrong, the vast amount of information is wrong. It's supposed to be a "simple" introduction to things but it severely veers off cliff on several things. The explanations seems to be actually copied, or may I say, "rewritten in OP's own words" (Probably why so much is wrong) from all over the place, with little actual knowledge on the topics. Some of the governor explanations really sticked out as painfully wrong and I corrected some of them.
I doubt OP can actually explain anything in this "guide", as I've said most of it is wrong and copied out of context. The zRam explanation is actually out of this world:
Disk paging doesn't even exist on a phone, unless you have a custom kernel which supports, and you yourself actually created a swap space. Fragmentation doesn't exist / doesn't matter on solid state memory.
This really shouldn't be a sticky, and people really would be better off following other guides.
MBQSniper is nothing if not helpful, patient, and kind when helping other users. None of us know everything. If we did, we wouldn't be here.
