summary
Explains Linux kernel CPU throttle mechanisms and the new CPU Burst feature merged in Linux 5.14, which permits short (~100 ms) CPU usage spikes when a pod’s average CPU use is below its limit. Describes how CPU Burst works, its impacts on application performance and CPU utilization, and how to evaluate whether to enable CPU Burst for your pods to avoid unnecessary throttling.
