END USER LICENSE AGREEMENT
nPerf aims to help you measuring the quality of your Internet connection. A bitrate test, as powerful as it can be, is not sufficient to characterize the quality of an Internet connection. That is the reason why we decided to develop a new way of testing your Internet connection in only few seconds, through a new process which is very similar to the way you are surfing on Internet.
nPerf is young, it is now too early to announce key figures.
The press speaks about us
The bitrate test relies on downloading binary files with multiple simultaneous connections in order to saturate your connection during a few seconds. We can then measure the bitrate accurately. The peak rate is corresponding to the average of 30% of the highest samples (50% when uploading). The average rate is calculated after having excluded 5% of the lowest and 5% of the highest samples.
The latency test is performed ten times. We calculate the minimum and the average values, as well as the jitter value (maximum variation between samples).
By default, nPerf engine uses TCP mode which is more efficient because it uses sockets directly without going through the browser. To use TCP mode, you need to access remote services on TCP Port 8080 . If the TCP mode is not available (port 8080 is blocked), then test is done in HTTP mode. In this case the requests are going through the browser. This works well for bitrates up to 100 Mb/s , but beyond, this mode reaches its limits.
Supplying a community database
Without you, nPerf would not exist. By using our application, even for free, you contribute in the project. Your tests supply the nPerf database and you are therefore helping in the development of nPerf tools and services.
Providing a dedicated server
You are a sysadmin, a web hoster or an Internet provider? nPerf can integrate your own server! The more servers we provide, the more relevant the tests results will be. For ISP, we can support the configuration and administration of servers. Contact us.
Which are the data collected by nPerf?
nPerf application only collects geo-localized statistics. There is no private data collected. Collected data are used to characterize operator networks. All collected data become the property of FH. Collected data are as follows: geo-localization, network information, device type and model, system version, tests measurements.
How are these data processed?
Data are compiled in order to be published by ourselves. They will also be used to display maps statistics on our Web site. If they are transferred to third parties on a commercial basis, these data will be made totally anonymous (IP obfuscation).
