Everyone knows 4 KiB memory pages just magically appear in the page table and OS kernel data structures with exactly the same computational and storage complexity as 1 GiB ones. /s in case it wasn't transparent. It's stupid egotists who get emotional and defend their "alternative facts".

That is unfortunately my reality working with other Java developers. I mean, it would be if it actually wasn't even worse than that. They are constantly pushing to create more "microservices" which is just just a misguided trend to spread your functionality over as many machines as possible and have your user wait until a graph of a hundred network calls finishes to get any simplest thing done. Then they spend huge amount of time trying to resolve performance issues and call me, a "performance expert", to try to help find ways to improve the situation. Then dismiss my calls to maybe modularize their applications using regular programming language mechanisms like interfaces and packages. Anyway... it's been quite long since I met a Java dev who even knows what MMU and TLB is. It's a rare candidate who knows what is a virtual memory in the first place.
