Host: Linux 3.14-rc5, AMD FX(tm)-8350 Eight-Core Processor, cpufreq set to performance, cpb disabled
Router: NETGEAR WNDR3700v2, 3.10.32-9
Target: OpenBSD 5.4, QEMU Virtual CPU version (cpu64-rhel6), 3300.54 MHz

Host <-> Router connected via gigabit ethernet.

I confirmed that my target can do >50Mbit to another server, netperf shows 128*10^6 bit/s / 108 * 10^6 bit/s.

SQM with link-layer none settings:
 * download speed: 46000 kbit/s, upload speed 50000 kbit/s (~95% of measured speed on ISP's speedtest site).
 * fq_codel (default)
 * simple.qos
 * link-layer: none
 * results: <sqm_on_none.png>

SQM off: <sqm_off.png>

SQM with overhead Ethernet overhead 30: <sqm-on-30.png>
SQM with overhead Ethernet overhead 22: <sqm-on-22.png>

Should I also run a rrul46/rrul46compete test?

Best regards,
--Edwin
