TEST / A-B0BPS / MODULE

BEFORE / AFTER NETWORK TEST

Measure two controlled network states around one change, then compare the factual differences without creating a universal winner.

CONTROLLED A / B LABREADY
CHANGE ONE VARIABLE WHEN POSSIBLE

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.

REFERENCE

Use repeated measurements and context rather than treating one number as an absolute diagnosis.
