How do you disable autotuning of TCP buffers?
How do you validate that buffer size is limiting performance?
How do you apply different buffer settings only to a specific interface (e.g., eth1)?
How do you test a buffer setting’s effect on large file transfer?
How do you detect TCP retransmissions due to buffer issues?
You suspect CPU resource contention on a RHEL 9 system. Use vmstat to monitor CPU usage and interpret the output to determine if the system is CPU-bound.
