Overseas users report that a city portal feels slow even though server CPU sits nearly idle. Distance to the hosting region is high. What is the most likely limiter?
Select an answer to reveal the explanation.
Short Explanation
If the servers are yawning with idle CPU but users across the ocean still wait, the delay is the long road, not the engine. That is network latency from distance. Spinning up more CPU will not shorten the trip across the globe — placement, edge, or CDN strategies might.
Full Explanation
Performance problems can stem from network latency independent of compute utilization. Geographic distance to the region increases round-trip time even when CPU is idle. Cloud+ optimization distinguishes latency-bound user experience from compute-bound saturation and points architects toward regional placement, edge, or content delivery approaches as appropriate.
