On the 5UF VPN (V5) home screen, the speed test sends a very small HTTP request to our dedicated test page. The page only shows your egress IP, so data usage is minimal and it should not meaningfully affect your allowance or billing.
The test measures network latency (how quickly you can reach a given node), not your maximum download speed. Unlike many tools that download large files to estimate peak bandwidth, we focus on round-trip delay to that node only.
We take multiple samples and show an average. Lower numbers mean faster response (lower latency) to that node.
