Linux Memory Management at Scale - Under the Hood

Explore Linux memory management at scale in this 53-minute conference talk by Chris Down from Facebook at SREcon19 Asia/Pacific. Dive deep into fundamental concepts crucial for site reliability engineers, including swap, cgroup v2, and memory protection. Discover how to build reliable memory-heavy systems, debunk common misconceptions, and learn about cutting-edge kernel concepts like PSI. Gain insights into scaling concerns, priority inversions, different types of memory, and the OOM Killer. Understand reclaim processes, physical memory limitations, and pre-OOM detection. Test your knowledge with a pop quiz and explore memory limits, roles, and protection in production environments. Enhance your ability to create stable and performant systems at scale through this comprehensive exploration of Linux memory management.
