Connection quality — latency, throughput and jitter
Gauge latency and throughput between your browser and our edge.
What it detects
This check measures the round trip between your browser and our edge — an approximate view of latency, throughput and jitter on your current path. Running through a VPN, it reflects the added hop to and from the VPN server.
The result is summarised as a coarse speed bucket (for example fast, medium or slow) rather than a precise benchmark.
Why it matters
A VPN almost always adds some latency and can reduce throughput; a large drop often points to a distant or congested server. Comparing with and without the VPN, or across servers, helps you pick a fast exit.
Connection quality also shapes streaming and video-call experience, which is why VPN users care about it.
How to read your result
Treat the bucket as a rough guide, not a lab benchmark — browser measurements vary with load and background traffic. If speed is poor, try a nearer or less busy VPN server.
We store only the coarse bucket, never a detailed performance profile of your line.
Frequently asked questions
- Is this as accurate as a dedicated speed test?
- No. It is a lightweight browser-to-edge estimate meant to flag obvious problems, not a precise multi-server benchmark.
- Why is my speed slower on a VPN?
- Your traffic takes an extra hop through the VPN server, adding latency and sometimes reducing throughput — more so if the server is far away or busy.
- What do you store about my speed?
- Only a coarse bucket such as fast, medium or slow — never a detailed profile of your connection.
