Sure, i will. You made my day =C2=A0:)
because b= y reading papers/articles, i didn't get that i gained from you people.<= br>
Infact always wanna hear something like this.=C2=A0

David Sir,

Thanks for answering.

can you please tell me how to interpret its output?

By=C2=A0 =C2=A0"netperf-wrapper rrul netperf.bufferbloat.net" ( i chose net= server
that is running on netperf.bufferbloat.net)
output(result.png) is attached.

please tell me first what does it say generally?
secondly,=C2=A0 anything related with bufferbloat point of view.

 latency should not increase significantly under load. The fact that it does= indicates that you have a problem. The fact that the latency can increase = to multi-second values for many people indicates a big problem.

take a look at the new test that's available at https://www.dslreports.com/spee= dtest and then look at the results tab and see how the latency increase= s during the download and upload tests.

If you have a system without excessive buffering, you would not see massive= increases in latency.

Contact me off-list if you want a deeper discussion of the history of buffe= rbloat and what's going on to try and solve it.<= font color=3D"#888888">
