Re: Ongoing issues with Single Thread Speeds

Hi

Just to add I've not had maximum throughput via Uno (which use TalkTalk) for many, many months on the single thread speed test, regardless of the time day or night, I usually get around 60-64Mbps on the single thread test, with the multi-thread test always ~74Mbps. I know when you first posted about this and I replied I was getting maximum on both types of test, but at some point that changed, although nothing my end has changed.

However playing about with TCP Optimizer https://www.speedguide.net/downloads.php I can improve the single thread speeds back up to almost match the the multi-thread speed, so I don't think it is something being deliberately throttled by TalkTalk, just some interaction between Windows (10 in my case) automatic network settings just not hitting an optimal match against TalkTalk and the site it's connecting to.  This may explain why some speed tests are okay and others are not.

Edit:  if I test here https://testmy.net/results and use the single thread speed test option I get consistently > 73Mbps, it's only ThinkBroadband's single threaded part of the test that is impacted, which I think was your original issue?  I think the problem is with Thinkbroadband and how the test is routed or network parameters and there isn't really any problem at all with the speeds, just the test.

Hi Phil,

Interesting that you are seeing a reduction in single thread speeds with Uno.  There's another IDNet customer on TBB who has been moved from a BTW backhaul with evening congestion to a TTB backhaul and seeing something akin to what I am seeing.  He's had his fill of IDNet and has just placed a migration order with Uno, so may give him a heads up of what you are seeing at Uno.

I've not done any TestMy.Net testing but did run their auto tests for a couple of days after joining IDNet.  As you can see from the attached graphs, the speeds were generally better, but there were some definite blips as well.  I might just try running a few manual tests back to back to see how consistent they are one after another.

Out of interest, have you tried running TestMy.Net in multithread mode to just the London server.  It just won't run smoothly for me.

Uno used to have a single thread tester, but they seem to have taken that off line.  I found that a useful reference point in the past, so it's a shame it has gone.

I'm running off a Mac, so speedguide.net tweaking is not an option for me.  I have validated my TBB results with my son's Win10 laptop, so fairly certain it's not the Mac at fault here.

Thanks,

Jon

Didn't AA have a similar experience with TT at some point? I can't remember.

Would AA suit you? They are very keen on performance monitoring.

They did.  At the beginning of last year IIRC.  Pulse8 had something similar when I was with them, which affected certain gateways and was unrelated to the AA issue.  That was fixed after about a month of investigation.

I'm not mad keen on going to AA for a couple of reasons:
1)  I've just paid for 12 months up front with IDNet and not willing to write that money off, unless I can negotiate a refund.
2)  I've still got an adult child at home and the other one threatening to come back at some stage, so not sure I really want to go on a limited bandwidth product offering.

They do remain an option for the future though.

For me the small niche providers arent what they used to be and I now consider risky, they dont have the benefit of large swarms of customers able to absorb heavy users like the large isps do and as such I actually now thing visible contention is more likely on smaller provider, AAISP I have as an exception tho as their managing director has always made a point of AAISP never been the bottleneck.

Done.  Results attached.  I then ran 5 TBB tests and got single thread results of: 71, 50.2, 67.5, 68.8 & 67.7 Mbps.  Better than I have been seeing off TBB, but not as good or consistent as TestMy.Net.

Hi

The question is, are we just testing the tester now?

There is something going on with TalkTalk I think and as Uno get handed off to Daisy this I would think points more towards their back haul. 

This is a test just now, not too bad for the single thread test but it the speed used to always been on parity with the multi-threaded speed, so it isn't' constantly around 10% less that I've often seen recently.  So probably congestion rather than a deliberate throttling, it's hard to complain as it is sold as a contended service, and it never gets any worse than a 10% reduction, and of course if a second person in the household is doing something online or we are streaming and downloading, we will be maxing out the line no problem. 

I wonder if this is some QOS setting on their network and is by design to reserve bandwidth for TalkTalks TV service?



Regards

Phil
