Scalability Issues in Linux Kernel

Scalability Issues in Linux Kernel

Explore scalability challenges in the Linux kernel during this 24-minute conference talk from the Linux Plumbers Conference. Dive into bottlenecks encountered in large CPU systems, including LOCKSTAT scaling issues, thread sharing problems, directory entry contention, and page reclaim inefficiencies. Learn about the need for improved frameworks in areas such as magic number tuning, locality strategies, and load balancing. Discover potential solutions for enhancing performance on machines with slow but numerous CPUs, and gain insights into VM scalability issues, massively parallel platforms, and connection socket optimizations.
