Use repeated measurements and context rather than treating one number as an absolute diagnosis.
BEFORE / AFTER NETWORK TEST
Measure two controlled network states around one change, then compare the factual differences without creating a universal winner.
Examples: VPN off/on, old/new router setting, access point position, SQM off/on, busy/quiet period. Keep other conditions similar where possible.
COMMON QUESTIONS
What should I change between run A and run B?
Change one thing at a time where possible: router setting, VPN state, Ethernet cable, access point, device position or time period. This makes the factual difference easier to interpret.
Does 0bps declare a universal winner?
No. It shows A, B and the measured differences. Faster throughput and lower latency can pull in different directions depending on your workload.
