Odd TBB test ?

[#1]

Ouch.  Yeah, that doesn't look anything like what we've been looking like.  Out of interest, what does their other speedtester show (and is that the old one?)

[#2]

As of 11:15 this morning, it's

But this tester normally gives reasonable results, as you can see from my other contributions to this thread

(edit, last nights test was their newer one)

gateway pcn-bng04. , my connection is like a roller coaster

I'm having the issue forward and reverse today.

I can't be bothered to turn of traffic shaping to show a silly graph.

@30FTTC06   i am sorry am at a loss , i dont understand Iperf  can you explain basically what i am looking for

Thanks

[#6]

Yeah it's a 10 second single threaded speed test showing the speed readings each second as shown on the left,

UDP or TCP as follows below, if your line is working as expected with no congestion etc you will get results as follows below. Just for the reference they were done one after the other about 15 minutes ago which is odd because all seems ok now!

Go figure..... anyway. if I'm getting a curve on a TBB test, you will also see that reflected in the figures on the right side of the test ie

  5mbps

12mbps

22mbps

30mbps

30mbps

30mbps

30mbps

Hope that helps!

[#7]

Just to note! some servers do udp while others don't, also for a fast line like yours you would be better off leaving the bandwidth flag OFF as follows

iperf3 -c bouygues.testdebit.info -p 5200 -R

 For Uploads do.

iperf3 -c bouygues.testdebit.info -p 5200

After a good weekend on gateway pcn-bng02.

i got a slight drop this morning http://www.thinkbroadband.com/speedtest/results.html?id=148939356205500636715

[#9]

well Mr Brokenreach have been at my Green box outside , thought i would try a test http://www.thinkbroadband.com/speedtest/results.html?id=148941386204064860183

[#10]

Normal tester - http://www.thinkbroadband.com/speedtest/results.html?id=1489434602245880555

Alternative tester - http://www.thinkbroadband.com/speedtest/results.html?id=148943468745455228182

(It has been confirmed today that my connection is below the lower estimate, but the above results are way below :()

Those look ok. (certainly not affected by this issue

My upload is faster than my synch rate - that's odd!

Hey @rongtw, we've come to the conclusion that whatever is going on with your line isn't to do with the issues we were seeing originally.  It looks like you get chunks of errored seconds on your line which may explain the random slowdowns and performance problems.  We've got someone raising a fault on your account to investigate for you.
