Broad band monitoring and Samknows


[link to this post]
 
Looking for a bit of advice.

I frequently suffer from a poor overall broadband experience most evenings at home in terms of download speeds, buffering etc. on my already slow rural connection. The degradation is often severe from 2.3Mb/s to sub 1Mb/s This is across a range of sites and appears if I run speedtest etc. but if I look at the samknows stats this rarely shows up as being an issue.

Does the little white box only create data points every few hours or is it internally checking more frequently. The cynic in me feels like some traffic is given priority e.g. samknows data verses normal use.

I have a Samknows box and speedtests run every 3 hours starting at 1am (although it seems to run one at 4pm then at 6pm at which point it goes back to 3 hourly - presumably looking at peak times).

It is very possible that the ISP might be prioritising Samknows data - or it could just be that Samknows use a protocol that would be prioritised anyway (eg HTTP).

What ISP are you on?

I hope not all SamKnows boxes run their tests at the same time - unless they are being paid enough to guarantee uncongested capacity on their host platform for all the boxes at once.

3000 boxes and an average 30 Mbps would mean around 90 Gbps was needed.

If you can what you need to do is just after a new test has been done by the samknows box is run other speed tests, and do them when connected via an Ethernet cable (thus avoiding wireless issues)

Our test at http://www.thinkbroadband.com/speedtest gives a URL to share at the end, and we record all the data not just the summary numbers, so the graph you get at the end can sometimes be more informative than the result itself.

The logged times are precise hour points - I haven't monitored the connection to see if that is when it goes through but going by the dashboard it appears to run at the top of the hour at 1am, 4am, 7am, 10am, 1pm, 4pm, 6pm, 9pm, 10pm and 11pm. It is the same every day. I will try and have a look somewhen to see if there does actually appear to be traffic at the top of the hour. If there is then my guess is all will be the same as it is too much coincidence that mine is at exactly x-o'clock.

My bet is that its logged at the hour, but takes place at different times, since even if it was just an average of 5 Mbps used by each box that would need 15 Gbps

My understanding was also that if it found you were using the connection it is meant to not run the test, and I assume monitors the network interfaces to do this and also kills the test off if it detects you starting to do something.

Thanks for the replies I'll try to run some tests as you suggest and reply to the thread for information purposes if nothing else.

While I see the data points on the online graph I wondered if this was a single test at the time point shown or the aggregate of a number of preceeding tests between data points.

To answer another point am on BT on a market 1 exchange

Understand that the time point (whether its really then or at another point in the hour) is the batch of tests run, so preceding tests should not change things. Certainly graphs from people with varying results show up and down, rather than a rolling average affair which is what your suggestion is.

If this is an ISP supplied box, rather than Ofcom it is possible its testing to a location on the ISP network, rather than wherever the SamKnows box tests to and from. So there is a possibility that the ADSL is perfectly fine and how the ISP is handling your traffic once you hit them is the issue.

I know the test execution is done at hourly intervals, but not on-the-hour. Proving it is a different manner...

In the reporting panel, the "Simple" tab gives results on the hour.
Like this:

24th Jan, 2017	01:00	68.70	68.70	68.70	1
24th Jan, 2017	04:00	72.64	72.64	72.64	1
24th Jan, 2017	10:00	72.22	72.22	72.22	1
24th Jan, 2017	13:00	72.43	72.43	72.43	1
24th Jan, 2017	16:00	68.67	68.67	68.67	1
24th Jan, 2017	19:00	70.37	70.37	70.37	1
24th Jan, 2017	20:00	72.61	72.61	72.61	1
24th Jan, 2017	21:00	68.71	68.71	68.71	1
24th Jan, 2017	22:00	68.70	68.70	68.70	1
24th Jan, 2017	23:00	72.71	72.71	72.71	1
25th Jan, 2017	01:00	72.27	72.27	72.27	1


However, if you swap to the "advanced" tab, then pick "raw test data", you get real times

24th Jan, 2017 @ 01:58:47	68.70
24th Jan, 2017 @ 04:58:01	72.64
24th Jan, 2017 @ 10:59:38	72.22
24th Jan, 2017 @ 13:58:21	72.43
24th Jan, 2017 @ 16:58:08	68.67
24th Jan, 2017 @ 19:00:45	68.18
24th Jan, 2017 @ 19:58:50	72.56
24th Jan, 2017 @ 20:58:58	72.61
24th Jan, 2017 @ 21:58:52	68.71
24th Jan, 2017 @ 22:58:31	68.70
24th Jan, 2017 @ 23:58:50	72.71
25th Jan, 2017 @ 01:58:28	72.27


I reckon SamKnows gets tests executed throughout an hour-long period, but treats them all in top-of-the-hour groups.

In the raw tests above, it looks like I had a test due at 18:58 that didn't execute until 19:00, which took it into the next hour. The simple panel then reports a single sample for 19:00 that has averaged the 19:00 test and the 19:58 test.

Go to the advanced tab, and check the "raw test data". Some tests are indeed made up from multiple individual results - such as the DNS response time.
