  • Most accurate internet speed test.
    You should try Flent from the BufferBloat project. Source: 11 months ago
  • Tools for measuring Network convergence, delay and packet loss
    Flent (Flexible Network Tester) is a powerful network testing utility that aims to simplify the process of gathering and analyzing network performance metrics. Built on top of other open-source tools like Netperf, Iperf, and Ping, Flent automates the process of running multiple tests simultaneously and aggregates the results into comprehensive, easy-to-interpret graphs. Flent's ability to run various tests in... Source: about 1 year ago
