Nice! It gives me what I'd expect for my setup, although the TCP rate is only 2/3 the line rate on DSL (upload is better at 80%).

..............................................................

Download: 14.09 Mbps

Latency: (in msec, 62 pings, 0.00% packet loss)

Min: 30.157

10pct: 30.691

Median: 33.412

Avg: 34.044

90pct: 36.970

Max: 48.250

..............................................................

Upload: 0.87 Mbps

Latency: (in msec, 57 pings, 8.06% packet loss)

Min: 30.655

10pct: 30.744

Median: 36.658

Avg: 36.379

90pct: 41.414

Max: 46.451

I'm running 21000/1100 as my rate-limiting settings in CeroWRT (3.10.32-12).

That packet loss is what kills my UDP ping streams. It doesn't seem to happen if I use the Free.fr box directly, and only shows when I use CeroWRT as the bottle-neck.

I have created a 'speedtest.sh' shell script that simulates the http://speedtest.net, but does it one better.

The default options for the script do a separate TCP_MAERTS and TCP_STREAM for 60 seconds while collecting ping latency. The output of the script shows the down/upload speed as well as a summary of the ping latency, including min, max, average, median, and 10th and 90th percentiles.

The script makes it easier to optimize my settings because it makes the latency figures more concrete. (I used to eyeball the ping output, saying, "Hmmm. I think there were fewer outliers than before...")

You can see the script on the "Quick Test for Bufferbloat" page on the wiki at:

Enjoy!
