average CPU use is twelve percent and the p99 latency is terrible, because the container is being stopped for milliseconds at a time.
CPU throttling
Also calledcgroup throttling, CFS throttling
The kernel pausing a container that has used its CPU quota within the current scheduling period. Because the quota is enforced per short window rather than on average, a workload that is bursty — which most request handlers are — gets throttled while looking idle in any per-minute graph. It is the most under-diagnosed source of tail latency on container platforms, and the metric for it is not CPU usage but throttled time.
