Also, holy cow, what's going on with your connection? The unloaded
latency says 17/110/200 min/median/max RTT. Is that due to bad
measurements, or do you have a lot of cross traffic and a really bloated
link? :/

The tests differ somewhat while looking at an unloaded residential link provided by a local monopoly, Rogers Cable, and mitigated by an IQrouter (my old linksys is long dead (;-))

DSLReports says

  *   144.7 Mb/s down
  *   14.05 MB/s up
  *   bufferbloat A+
  *   downloading lag 40-100 ms

Waveform says:

  *   43.47 Mbps down
  *   16.05 Mbps up
  *   bufferbloat grade A+
  *   unloaded latency 93.5 ms

So we're reporting different speeds and RTTs. Are we using different units or definitions, I wonder?
