Re: [Bloat] [Rpm] Ookla - Introducing a Better Measure of Latency

This is very cool! I'm glad to see them embrace "download ping" and "upload 
ping".

Re: [Bloat] Ookla - Introducing a Better Measure of Latency

[Klatsky, Carl via Bloat]

Its good that they are running the latency test also during the load test, but 
from what it looks like, they seem to be running the latency test to the same 
server as the load test.  I think a more realistic test is to run the load test 
to one server and the latency test to a different server.  That's a more 
realistic use case...

Carl Klatsky

I'm not aware of any rigorous study. But, just from the code, I know ICMP ping 
in many cases has a different traffic-class and thus implicitly gets quite a 
different treatment than real traffic.

However, Ookla uses TCP (port 8080) to probe the latency in their app.

Re: [Bloat] Ookla - Introducing a Better Measure of Latency

[Sebastian Moeller]

Hi Christoph,

nice! Thanks for posting.


For Android (and iOS) Ookla's speedtest app now reports a "Detailed result" 
page which contains:
1) Upload and download rates (albeit without information what exactly was 
measured) 
2) Data volume used per direction (but not the precise duration of the test)
3) Idle, download, upload responsiveness measures:
(probably) the average, the jitter, the minimum, and the maximum
4) Packet loss percentage

This is quite an improvement and achievement! I would wish for a bit more 
information about the details, like how was latency exactly measured, how many 
probes were used per direction and what are the individual delay values...

Unfortunately, the macos client seems not yet updated and the web based test 
also still only reports the idle RTT. I hope it is only a matter of time for 
those to be updated.

Regards
Sebastian

a ping by any other name...

Has anyone ever done a rigorous study to see how well ping delays 
correspond to the delay that information-carrying packets experience?

This will hopefully be a shift in how operators approach the bufferbloat 
problem.

Ookla's measure of "loaded latency":

This will hopefully be a shift in how operators approach the bufferbloat 
problem.
