  • WAN circuit testing
    I think such a tool is fairly straightforward to develop with iperf 2 as the underlying src/sink. The man page has new features including start times & permit keys. Active, low duty-cycle, low impact telemetry has been a goal. The idea is that someone else would develop a web app and host public servers. As an iperf 2 maintainer, I'm trying to remain arm's length from such products but I do think the industry... Source: over 1 year ago
  • WAN circuit testing
    Iperf 2 can help and has many new tests including one way delay, low duty cycle burst, tcp bouncback, etc. More on the man page. OWD does required clock sync. Source: over 1 year ago
  • Is iPerf test an officially approved RFC 2544 test?

  • Is this good speed?
    Websites like speedtest.net, fast.com and etc do provide measurement in megabits, and even with that, speedtest.net provides it between you and your ISP(mostly) only. So if you want to download something from lets say, YouTube, the speed will be slightly different because now you're connecting to Google's server, not your ISP's server. This is because speedtest.net has partnership with ISPs so that speedtest.net... Source: 6 months ago
  • Help!!! FPS AND downloading games speeds.
    If fast.com and speedtest.net are fast, then it's not the computer or your internet. Source: 6 months ago
  • Internet shuts off when downloading
    If you try a speed test with only your PC connected via LAN (visit fast.com), do you get reasonable upload and download speeds? Are the speeds consistent? Source: 6 months ago
