SpeedTest Master

Test your ADSL, xDSL, cable, optical fiber or satellite broadband connection bandwidth. 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 speed test is compatible with all broadband and mobile connections: ADSL, VDSL, cable, optical fiber FTTH / FTTB, satellite, WiFi, WiMax, cellular 2G / 3G / 4G (LTE), 5G. The nPerf speed test has been designed by telecom enthusiasts to enable you to accurately measure the speed of your Internet connection easily, in only one click! Oh... and this speed test is absolutely free of ads! 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 speed measured in megabits per second (Mbps), how fast your computer can receive data from a server on the Internet. Upload speed, how fast your computer can send data to a server on the Internet. Ping, also known as “latency”, measures the reaction time of your Internet connection by calculating the time it takes between sending out a request to getting a response. Measured in milliseconds (ms), ping indicates how responsive your Internet connection is. Jitter, based on multiple measures of pings, jitter measures the consistency of your Internet connection. Also measured in milliseconds, the smaller the jitter, the more stable an Internet connection. Speed Test works with a global network of over 5,000 testing servers. The app selects a server nearby your current location with a fast ping, which usually indicates a reliable Internet connection with good throughput.
