Hey HN, I have built a game server orchestrator from scratch, As a solo-dev it took me 3+ years and almost 10 hours daily to finally complete it since i started in the beginning of 2023. Im 26 years old now!. The complexity and stuff i had to research to complete this project i couldnt have imagined them even in my dreams, but hey, here it is, my greatest professional achievement until now. Down below I will try to break down just some of the core and most important features of my game server orchestrator. 1. CORE PINNING & CCD CACHE ALIGNMENT I had to research and understand CPU cache layouts. I found out that if my game containers, which utilize docker run, span across different core complex dies (CCDs) or share SMT sibling threads with a busy neighbor, L3 cache thrashing ruins single-core tick efficiency. Then what I did is that I pinned all non game-server processes strictly on core 0 and its SMT sibling core 12 using GRUB: I disabled the 1000Hz timer interrupts to prevent context switching so as to not pollute the L3 cache. I also offloaded the rcu to cores 0 and 12 so as to avoid any micro interruptions on the game containers and leave 100% of the performance to th...
