LEARN · FROM TERMS TO DECISIONS
Make sense of VPN test results.
Start with the question you have, rather than a wall of technical terms. These short guides explain what each measurement means and show you where to use it.
YOUR NEXT STEP
Four numbers, different jobs
Download speed describes throughput. Retention adds a baseline. Latency describes delay. Packet loss helps you understand reliability.
CHOOSE YOUR STARTING POINT
What do you want to understand?
“How much speed does the VPN keep?”
Start with retention and the paired no-VPN baseline. Raw Mbps and percentages answer different questions.
“Why does it feel slow or unstable?”
Read latency for responsiveness, packet loss for missing packets and P10–P90 for variation.
“Which protocol should I try?”
Begin with the choices your app offers, then connect those differences to comparable measurements.
THE SHORT GUIDES
Build the missing piece of understanding
Each guide connects an explanation with evidence you can inspect. Read the definition, the common mistake and the practical next step.
Speed retention
Understand the VPN-to-baseline percentage and why the baseline matters.
P10–P90 and consistency
See what the central spread of repeated observations tells you.
WireGuard vs OpenVPN
Put protocol trade-offs in context before using benchmark figures.
OpenVPN UDP vs TCP
Understand transport behavior and the conditions that can change it.
USE WHAT YOU LEARN
Read one result with the full context
01 · Choose a test source
This is the lab worker where the measurement starts. Keep it fixed when comparing setups.
02 · Match the exit and window
The VPN exit and time period affect the comparison. Check that both sides have usable coverage.
03 · Read more than the median
Use retention, latency, variation and sample count to decide what the result actually supports.
