VPN Speed Test Guide
RookSpeed measures this service path only. Use it to compare relative change when you connect or disconnect a VPN.
RookSpeed reports median latency plus download and upload against this endpoint.
Fair comparison
Run once on VPN and once off VPN on the same network. Close large downloads between runs. Wait a minute so buffers drain.
Reading the numbers
Latency matters for calls and games. Download matters for large files. Upload matters for video calls and backups. VPN overhead often lowers throughput more than it raises latency.
Not a universal speed score
The result does not predict speed to every website worldwide—only to this test path.
