A city department's large file transfers between regions crawl even though CPU on both ends is mostly idle. Engineers suspect path MTU problems or thin links. What troubleshooting focus best matches the symptoms?
Select an answer to reveal the explanation.
Short Explanation
Idle CPUs with snail-speed copies usually mean the pipe—or the packet size the path will carry—is the bottleneck, not the processors. Measure latency, throughput, and MTU along the route before you buy bigger VMs.
Full Explanation
Throughput issues with low CPU utilization often point to network constraints: limited bandwidth, high latency/loss, or path MTU mismatches that cause fragmentation or silent drops. Valid troubleshooting measures latency and bandwidth and tests for PMTUD black holes along the path. Adding vCPUs, disabling encryption, or replacing TCP with ICMP does not correctly remediate path capacity or MTU problems.
