[Bloat] Getting started with sqm-scripts - latency good, bandwidth decimated

[Brandon Applegate]

Disclaimer: if this is the wrong list for such a question - let me know.  This is specifically about the sqm-scripts package...

Hello,

I’ve been reading all I can on the bufferbloat website and also trying to understand the evolution of the various scripts (debloat, sqm, etc).

I managed to get sqm-scripts on my firewall (Ubuntu linux on a PC - no *wrt etc).  Got it built with the ‘linux’ platform.  Since this is Ubuntu 12.04 - I had to cheat a bit and pull down the iproute2 source from 14.04.  I’ve tweaked the main sqm script to reflect this for the tc bindary - this is working.  I also updated my kernel to a later version that supports fq_codel.

My topology is ‘on a stick’.  I have one gig interface to a managed switch, on which are eth0.666 (outside/wan) and eth0.10 (inside).

I have 30/5 cable service, and have tried both those values as well as 90% in my /etc/sqm/*conf file.

I’ve tried both eth0 (raw/parent interface) as well as eth0.666.

No matter what I do - my bandwidth is 10% of what it should be.  I get approx. 3/4mbit down + 2/3mbit up on dslreports speedtest.  Bufferbloat looks great though - A+.

Is there something inherent I’m doing wrong ?  Something to do with my ‘on a stick’ topology biting me ?  Kernel version (Ubuntu’s 3.13.0-74-generic btw).

Thanks in advance for any help or info (or pointer to a more appropriate list).
