Re: Comcom/Samknows broadband testing from a different perspective

Hi

Since putting the device on the Enable Network, I’m actually not overall happy with the results I'm seeing.

There is an inconsistency with the Download/Upload Speed, Latency and Jitter.
When testing using another Testing service such as Speedtest.net and Fast.com, Iperf  are consistently report my connection speed as 950Mb/s Downstream and 500Mb/s upstream.

Samknows is reporting this My peak connection Speed for download of 742Mbp/s and upload 429Mbps, but these results are not consistent when I compare other speedtest services.


According to the data provided from Samknows user analytics, they are testing the download speed on the hour between 6 pm and 11 am daily and one sample at 5 am.
These times represent Enable network peak and off periods for traffic.


     *   The graph below are taken over a 7days period, sampling every 30 seconds at a bit per second.
     *   Have another member of NZNOC got similar testing results to mine
     *   What I can’t answer is how the data in the graphs below is represented by Samknows.

Note:
The Samknows device is the only (Connection) plugged into this GPON interface.
There is other user traffic been generated on this port other than samknows device.

OpenWRT/LEDE binary, Just shell on.. opkg update, -i what you need..., netstat -antop | grep EST this will surprise you, dest will surprise you more then I  put in the green wheely.  On the WAN link you may see lots of src privates indicating typical dinky rtr/fw nat not coping similarly actual/true $paid for bandwidth at src (home) = rubbish + legit flows. rubbish flows (in/out) of breaks packet concurrency increasing delays and maxin out (netflix/gaming stream) PDVs on clients - recommend filter|block upstream of router will lead to a huge improvement in media quality and performance of your home router.

good luck - regards brian
