CPU Burst - Getting Rid of Unnecessary Throttling, Achieving High CPU Utilization and Application Performance at the Same Time

Explore the innovative CPU Burst feature introduced in Linux 5.14 to address long-standing CPU throttling issues in this informative conference talk. Learn how this new approach allows for high CPU utilization and improved application performance simultaneously, even when average CPU usage is below set limits. Dive into the kernel mechanisms behind CPU limits enforcement, understand the changes brought by CPU Burst, and discover how to evaluate its impact on your pods. Gain insights into choosing appropriate CPU hard limits and overcoming challenges associated with traditional solutions. By the end of this presentation, acquire the knowledge needed to determine whether implementing CPU Burst is the right choice for optimizing your container performance and reducing total cost of ownership.
