What's nPerf speed test ? How does it work ?

nPerf qualify accurately your internet connection's performances.

This speed test relies on an exclusive algorithm allowing you to measure accurately download bitrate, upload bitrate and latency of your connection.

nPerf uses a worldwide dedicated servers network, which is optimized to deliver enough bitrate to saturate your connection, so that we can measure its bitrate accurately.

nPerf is compatible with all broadband and mobile connections: ADSL, VDSL, cable, optical fiber FTTH / FTTB, satellite, wifi, wimax, cellular 2G / 3G / 4G (LTE).

Latency (ping)
Indicates the delay a small packet of data requires to make a round-trip from your computer to the nPerf server. The shorter the delay, the most reactive is your connection.

Download bitrate
Indicates the amount of data your connection can receive in one second from the nPerf server. The highest the measured value, the best is the bitrate of your connection.

Upload bitrate
Indicates the amount of data your connection can send in one second to the nPerf server. The highest the measured value, the best is the bitrate of your connection.
