Subject: [Flent-users] interpreting my RRUL results

This rrul test was run in a Linux Mint VM on a computer directly connected to my Arris BGW210 DSL modem, carrying my AT&T provided service at 75/20.

My original plan was to analyze buffer bloat from machines behind my router that is behind this modem, in case my performance would increase with a Ubiquiti Edgerouter that supports shaping algorithms such as cake.
However, I thought I had better first see what impact the modem itself has on the  buffer bloat situation.

Below is the standard unscaled triple plot from rrul. It looks pretty awful to me, but I am not experienced in reading these.
I would be grateful for help in interpreting these graphs, and for any suggestions on what, if anything, I can do (buy an IQrouter, perhaps)?

Also, I would imagine that,  the best I could do with a traffic shaping secondary router would be to not make things any worse. Would that be correct?

Many thanks for any education and thoughts about what to do next.
