<div dir="ltr"><br><div>Well Sebastian sir, I am taking your advice and I'm on windows 7 so right now I'm downloading virtualbox and xubuntu. I don't know if there is one that you guys recommend. Well... I am new to all this stuff so I'm asking you to please help me on the subject like after everything is up and running on the computer, what other steps do I do afterwards and forgive me like I said I'm new ot all this stuff because I want to be able to find my link capacity when using SQM. and Thanks for the help!</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Oct 19, 2014 at 3:55 PM, Sebastian Moeller <span dir="ltr"><<a href="mailto:moeller0@gmx.de" target="_blank">moeller0@gmx.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Ernesto,<br>

I would recommend to not run the netperf processes on the router you want to assess, if possible. Shaping at the rates you are interested in probably will take 100% CPU of the router, so there is no slack for running net server and netperf instances at the same time. Also I would recommend to use netperf-wrapper (<a href="https://github.com/tohojo/netperf-wrapper" target="_blank">https://github.com/tohojo/netperf-wrapper</a>) instead of netperfrunner.sh as it allows so much nicer visualization of the queueing over time. netperfrunner.sh is great tool for quick testing and figuring out link capacities and worst case latency under load increase (LULI), but for more thorough comparisons it ain’t made. Netperf-wrapper will run under linux and macosx natively, but will also run (well enough) in a linux virtual machine on a windows box.<br>
<br>
