For the love of god stop using CPU limits in Kubernetes
Kubernetes CPU limits significantly degrade application performance and increase infrastructure costs by throttling apps to 10+ times per second, even when cluster resources are available, while CPU requests alone provide adequate protection through fair scheduling. Organizations using CPU limits are likely experiencing hidden performance degradation (masked by averaged metrics), paying tens of thousands of dollars annually in wasted compute, and suffering from poor tail latency under peak traffic. IT leaders should audit their Kubernetes configurations to remove CPU limits while retaining CPU requests and memory limits, enabling faster applications, better resource utilization, and substantial cost savings.
