Well, that's basically it.
The author appears to have heard some explanations on Unix & OS internals, but not quite understood them and appears to confuse a lot of things. From the looks of things, I figure the author did some voodoo problem solving and then, convinced of having understood the problem, decided to write an article about it.
There's a lot of second guessing, e.g. what the mmap flags do, based solely on their name, resulting in the bizarre connection to security guarantees; casually dismissing over-commit (because "nobody would do such a thing"), etc...
- formerly_proven 5y agoThis reminds me a little bit of a lengthy blog article by some FAANG engineer about picking optimal chunk sizes for I/O where he did a lot of benchmarking with /dev/null and /dev/zero.
