Cilium offers a range of tuning parameters that can significantly impact its performance, functionality, scalability, and resource usage. Understanding the effects of these parameters is crucial for optimizing Cilium deployments, but this task can be complex and time-consuming.
This session will explore the development and implementation of a Test Suite, highlighting key tuning parameters like adjusting the maximum number of BPF maps or the frequency of connection tracking garbage collection. It will showcase the methodologies used to test these parameters, including automated performance benchmarking and resource monitoring to provide a framework for systematically evaluating the impact of tuning parameters under various workloads. Attendees will gain insights into the challenges and best practices of tuning Cilium, as well as the benefits of incorporating such a Test Suite into their CI/CD pipelines.
