[Cerowrt-devel] No legend for netperf-wrapper graphs

Hi there,

I am a bit grumpy right now, since it seems as if my router just died on me (trying an "emergency" flash to 3.10.6).

	The buffer bloat effort is mostly driven by enthusiasm not monetary gains. So as I understand it netperf servers are run by volunteers out of their own pocket. Given that a number of ISPs have maximum transfer volumes by months I think it actually is amazing that there are some server available at all. I think that no one would complain and rather support it if you would volunteer to set up a netperf server to remedy your observed lack of openness, allowing others to test against your router. :)

	Now have a look at https://github.com/tohojo/netperf-wrapper/blob/master/tests/rrul.conf, and http://en.wikipedia.org/wiki/Differentiated_services you can get a pretty good overview of what the diffent line colors per plot actually mean. My take is for the ADSL encapsulation tests all that matters is the average and the fact that is is averaged from 4 flows, so mentally multiplying the y-axis by 4 gives an idea about the total bandwidth used. The interesting stuff happens in the ping RTT plots, which you want to be as flat as possible with preferably no big increase once the TCP loads start.


Best Regards
	Sebastian

I can let you (or anyone else that asks) know the addresses privately... I will probably add one in Japan soon and we continue to look for a hosting service that will actively help....
