Are there others? What is your preferred one and why?


​Generally I don't bother with speed testers unless I'm wanting a quick
guesstimate -- I wouldn't recommend using them as a measure of how "fast"
an internet connection is because there's always other factors in
contention, and it only tests the path to the speedtester.

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!
