Diagnose Slow Network Throughput Including Containers
Together AISoftware Engineer · Technical Screen
Last updated
Investigate slow network throughput across application, transport, host, and container layers using controlled comparisons, retransmissions, limits, and path behavior.
A service has unexpectedly low network throughput, including when running inside a container. Explain how you would isolate the bottleneck.
Constraints & Assumptions
The source asks for a low-speed investigation and container-specific reasoning. No protocol, topology, or network provider is fixed. Distinguish application processing from transport and infrastructure limits.
Clarifying Questions
Is the problem throughput, latency, connection setup, or intermittent failure? Which endpoints and paths are affected? Does the same workload behave differently on the host and in the container?
Follow-up questions
- How can a CPU bottleneck resemble a network limit? Why might a single connection underuse available bandwidth? What would you compare before blaming the container network overlay?
