I do keep hoping it's really the browsers misbehaving.

My measurements are showing those kinds of delays are in the client
network but I don't know enough about this set up to know what's
going on.

If anyone is interested, I'm talking about some recent measurements at
the IRTG MAPRG meeting that is Thursday morning Korea time. I'm
guessing there's not much interest though since I had no comments on the
previous measurements though a fair number of people downloaded my
writeup.

The command line tool is available to anyone now (Windows, OSX and linux),
it does buffer bloat probing, using ICMP if run as root, and is immune to
any browser issues. It can be downloaded here from the sticky:
   http://www.dslreports.com/forum/speedtestbinary

So the task remains to find someone with (a) 250+ megabit/second, (b)
showing bloat in the browser, and (c) is prepared to patiently verify it is
a real thing.

As I am deeply respectful of cultural differences, and yet often
ignorant of many of them, would my appropriate behavior in australia
be:

A) Kisses on both cheeks?

B) A beercan bump?

C) A high five?

D) Throwing 10 lbs of shrimp on your barbie?

E) Something other than the above?

As a Pommie myself, I assume this would be most appropriate, given that it’s currently summer down there.

But I could be wrong…

Well, getting in front of an audience always helps.

Yeah sorry the forum software zipped up the attachment and thus loses the
executable permission flags. I'll attach zips to the post instead which I
think will fix that.

This does not seem to be reporting any bloat info (I've run it a couple times)

It has to run as root / Admin in order to do ICMP in order to test buffer
bloat.

If you run it under a non privileged user account it cannot get permission
for ICMP, so although it locates the nearest servers using http ping, it
isn't doing any buffer bloat testing.

I'm not sure that is the issue but that's the first thing that comes to
mind..

I had the same problem, getting no bloat report. I tested just now 
running as root, and got bloat measurements in 
http://www.dslreports.com/speedtest/6166098 and 
http://www.dslreports.com/speedtest/6166295

 From Firefox, I get somewhat higer latency (~100 ms) versus ~20-60 ms 
via the command line client:

http://www.dslreports.com/speedtest/6130740
http://www.dslreports.com/speedtest/6130727
http://www.dslreports.com/speedtest/6130708
http://www.dslreports.com/speedtest/6130690


Two things to note:

- Firefox tests were run yesterday at around lunchtime  (~12.00 CET), 
and CLI tests just now (~06.40 CET). So time-of-day effect may be a 
reason for less bloat now. I'll do a better comparison when I get to my 
desktop.

- CLI tests were run in a docker container, for security purposes. I 
used host networking so it should not have affected measurements much, 
but still. This was how it was executed:


// downloaded the dslreports cli tool to my host /tmp directory, mapping 
/tmp to /host in the debian container

$ docker run --rm -t -i -v /tmp:/host:ro debian

root@db0ea060caa7:/# apt-get update ; apt-get install ca-certificates

root@db0ea060caa7:/# /host/dslrcli-linux-amd64

Download Testing.....
Upload Testing.....
Uploading results...
Download : 883.56 Megabit/sec Upload : 895.32 Megabit/sec
http://www.dslreports.com/speedtest/6166098



A better option would be using CAP_NET_RAW, I'll see if this works 
instead of running with full root privs.

I've done tests with CLI, Firefox and Chrome; repeated 3 times in
a round-robin fashion (cli, ff, chrome, cli, ff, chrome, cli, ff, chrome).

In summary:

- There is 5-10 ms additional latency during all tests.
- CLI and Chrome have the same latency figures, 23 ms base latency 
  Firefox has a base latency of 100 ms RTT, most likely due to US
  responders being used by Firefox and EU responders being used by CLI and Chrome.  
- Chrome achives 30-40 Mbps higher throughput than CLI.

Yes, copying the binary to /usr/bin and setting cap_net_raw made it report bloat.
(sudo setcap cap_net_raw+ep /usr/bin/dslrcli-linux-amd64)

Hi Stefan,

The reason for the higher latency is the auto-selection of the servers, the
IP address you were on for the browser tests was for a reason I can't yet
work out, only offering US servers. It is surprising that you got a
gigabit, pretty much.

You can avoid this problem in the browser test by selecting manually, using
test preferences, only euro servers and it will use the nearest of those.

The command line test was pinging all 76 servers so it used euro ones.

So my reaction from your tests is that the in-brwser buffer bloat testing
is probably accurate even at high speeds and with the same servers,
probably returning the same measurement.

thanks
-Justin

Apparently there is not enough duration currently: there is actual buffer
bloat data in your results, but it is insufficient in quantity so the site
isn't bothering to show and interpret it. Can you try one run by extending
the duration of download and upload phases?

if that doesn't work I'll have to patch the binary to make sure there is
always enough, and upload a new one..

thanks

my run was on 16.10 and I extended both upload and download to 45 sec.
