Accelerating Linux Boot Time: Techniques and Strategies for Optimal Performance - Lecture

Explore techniques and strategies for accelerating Linux boot time in this comprehensive DevConf.US 2024 conference talk. Dive into measuring boot performance using systemd-analyze tools, optimizing systemd through parallelization and service management, and implementing kernel and initramfs optimizations. Learn about Expedited Read-Copy Update (RCU) mechanisms, the advantages of the Efficient Read-Only File System (erofs), and methods for initramfs minimization. Gain insights into advanced topics such as udev configuration, storage module optimization, and device-specific enhancements. By the end of this 37-minute session, acquire a thorough understanding of how to achieve faster boot times and enhance overall performance in Linux systems.
