Docker and CI/CD · Senior · Question 20 of 75
A Node service has a CPU limit of 0.5 and shows latency spikes under load. Why?
- 1Node can't use more than half a core in any container
- ✓Correct answer: CFS quota throttles it once the period's budget is spent
- 3The garbage collector is disabled under CPU limits
Explanation
The process can burst, burn its quota early in each 100 ms period and then wait. Watch throttling metrics; many teams set requests but avoid tight CPU limits.
