[Bloat] New speed/latency/jitter test site from Cloudflare

[Dave Taht]

Dear John:

I am primarily an email person. But if github is the best way to
engage, we can do that.

My own bugaboo is that it helps a LOT to verify your test is measuring
what you think it is, via using another tool. In
our case that's flent (typically the rrul test), which gives correct
results past 10Gbit. Most of the web browser based tests
start to struggle > 200mbit.

I'd so LOVE to be able to put the basic requirements for flent
(netperf and irtt) on more servers around the world...
