I've used Visualware's My Connection Server, and the stats it gives are decent. Haven't yet updated to the latest version, which seems to be require client software installation, however. http://www.myconnectionserver.com/ Have also used Ookla's, but it seems more useful to join their speedtest network, than host the standalone, now. ---- On Tue, 06 Dec 2016 07:28:55 -0600 Matthew Walster <matthew@walster.org> wrote ---- On 5 December 2016 at 14:50, Graham Johnston <johnstong@westmancom.com> wrote: > Are there others?

Having said that, despite the obnoxious adverts on the site, speedof.me provides a really nice non-flash interface that is an excellent teaching tool for showing people how TCP congestion windows work, and lets you demonstrate to people the effect of buffers in a network etc. I'll be taking notes if anyone provides anything else similar that does a similar (if not better) job, maybe one that can be self-hosted too!
