There were a *ton* of juicy measurements from the TCP stack when = you click the Advance results button. But - you guessed it - no latency = measurements.=20 So I sent them a note and within an hour (on a Saturday!) I got a note = back from a real human. (Apparently, they've just rolled out the = service, so they're working hard to be responsive to all comers.) I gave them the whole story about bufferbloat, and how valuable it would = be to have those latency measurements. The initial reaction (on a = Saturday) was sincere interest but no promises because they were just = rolling out the service.=20 It turns out that CIRA is using M-LAB for their test infrastructure. = When I first looked, that project seemed dormant on Google Code - not = updated recently. However, they just moved NDT to github = (https://github.com/ndt-project/ndt) a couple weeks ago. And on = http://www.measurementlab.net/tools/ndt they mention a websockets = (non-Java) version of the web test page. So perhaps there's hope for yet = another good test suite.=20 I sent my note to the generic IPT@cira.ca. If a couple more people sent = notes of encouragement, perhaps they'll move it up in their queue. And does anyone know about Measurement Labs? How might we cajole them = into adding a bufferbloat/latency test? Rich=
