In Kubernetes, CPU is at 60% of the limit, yet p99 latency spikes. What should you check?
- 1CFS throttling: the container uses its quota early in each period
- 2Whether the container image is larger than 1 GB
- 3Whether the pod's memory limit is twice the CPU limit
Show the answer
Correct answer: CFS throttling: the container uses its quota early in each period
Explanation
CPU limits are enforced per 100 ms period. Bursty work can use the quota fast and wait the rest, even at a modest average. Check throttling metrics.
