I have today been using flent=C2=A0to do RRUL tests with t= he values set at 50%.

I have uploaded the first test I h= ave performed. It can be seen at,=C2=A0http://imgur.com/6DrMJKI.

I'm a bit confu= sed why the DS speed is only 7Mb/s when every other speed test I have done = is around 28Mb/s (as it should be). Can anyone explain why this might be? A= m I doing something wrong?

I would appreciate an e= xpert analysis of the graph, if possible :)

Yes, that is what I see as well.

=C2=A0 =C2=A0 =C2=A0 =C2=A0Yes, that should work.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 Should work, but also Ethernet should work, as = long as you do not specify anything, or rather -14 ;)

Yes. In essence that is the trick, it might make sense to look at cake'= statistics especially the max length field, which if you have lla set at n= one reach 1514 if the kernel automatically adds it's 14 bytes.

=C2=A0 =C2=A0 =C2=A0 =C2=A0 Only if you despise the GUI or only have= ssh access, I guess... Functionally it should boil down to the same, as th= e GUI simply fills /etc/config/sqm with values and then calls /etc/init.d/s= qm to actually start the scripts...

Best Regards
=C2=A0 =C2=A0 =C2=A0 =C2=A0 Sebastian
