K8s Interview Question: Why Is My Application Slow Even When CPU Is Low?

In this video, I explain a common Kubernetes interview question: why an application can be slow even when CPU usage is low.

I walk through a practical, step-by-step debugging approach used in real production environments. Starting with pod-level metrics, I show how to identify deeper issues such as disk I/O waits, node pressure, storage latency, network bottlenecks, and memory pressure that are often hidden behind low CPU numbers.

This explanation connects Linux fundamentals with Kubernetes concepts, helping you understand where performance issues actually occur inside pods, nodes, and the kernel.

If you’re preparing for DevOps or Kubernetes interviews, or debugging slow applications in production, this video will help you build the right troubleshooting mindset.
