Single thread issue


[link to this post]
 
Seems that come the evening Single Thread issues hit vodafone?

Rubbish early evening performance:

Working one later yesterday evening:

Initially I thought this was a wireless issue at home, but just experienced it on my wired machine, which was testing fine yesterday. Anyone else experiencing this?

Past experience suggests that you need to ensure you can describe how this impacts on some daily task, as providers are increasingly just citing testing that uses massively multithreaded results.

Pretty sure that Cisco AnyConnect will be impacted as it makes a single connection back to the mothership for secure comms.

If this only happens in the evenings it won't be too much of an issue, but if it occurs during the day then working from home could be seriously hampered.

At which point many consumer ISP will say they don't support business use and turn their backs.

Just started a download from my MSDN account - 6hrs for a 2.6GB DVD iso.
~150KB/s according to Chrome

Although a single thread test has just been significantly better than it was an hour or two ago:
https://www.thinkbroadband.com/speedtest/15138667368...

So basically Vodafone are suggesting the way to download files is via a torrent, as it stands, this service is basically worthless at random points during the day. What I can't understand is why sometimes the TBB single thread test is slow - possibly 10 times slower than the multi-thread and other times it isn't. Any thoughts?

*edit*
A few minutes after I started the ISO download, I also kicked off the VS2017 installer, which downloads lots of small files. That has downloaded just over 1.3GB in 6 minutes, where the ISO download has managed a stonking 128MB in about 10 minutes blush

Why 10 times slower when just 6 to 8 downloads in multi thread?

Without real time access to everything end to end impossible to say, and if issue is congestion which looks likely then the effects can vary greatly unless its a real network meltdown where they are sat at 100% utilisation 100% of the time.

If it gets to the point that video is buffering then you have a easier route to complain as that is a very common use, and it may be that this is fine e.g. if lots of on-net video caches then actual issue may be the routes through and out of Vodafone - a similar scenario to what Virgin Media have had on/off for ages.

It is a tad odd to say the least and if you fire up speedtest.net (the vodafone mandated tool for speed checks), it connects to their newbury servers and offers great results even when other downloads struggle (guess it uses many concurrent downloads to help make the internet look to be a faster place than it really is!)

That kind of implies there aren't local issues, but it is all in Vodafone's breakouts from the old C&W network to the real internet....

I have a SamKnows box, so will be interesting to see how that sees things from the change over from Sky to VF.

*edit - 16:15*
ISO download now at steaming along at ~90Kb/s, eta 6hrs (still!) with a massive 962MB download!

ran a speed test.net against IO Mart, which showed a download speed of 13.88Mbps from the normal vf ~36Mbps (upload was better though!). Definitely looks like it is their "connectivity" to the rest of the world!

Yes I do experience this - I've been with Vodafone for 3 months and the evening Single Thread speed is usually slow but at all other times in day I get max speed.

I was with BT for 2 years and there was no difference in speed at any time of day - I got max speed at all times and the fibre box is directly outside my property.

This isn't a problem for me and I'm pleased with the service particularly the price.

Crumbs!

I'm thinking of switching from Talktalk to Vodafone next month, not sure now after seeing those speeds!

I can download a ISO a lot faster on Talktalk.

Can't you tell speedtest to connect elsewhere?

As I started this thread, a quick update in order - although I'm not quite sure what to say.

Some minutes performance is terrible (even on a threaded speed test) and then minutes later is is back to looking ok.

I'm sure that performance isn't as good as when I was on Sky, but that is only a feeling. Things worked back then so I didn't really have the need to monitor things. I do have a Sam Knows white box, so I shall look back over the graphs it generates and see if there is a noticeable drop in performance.

Also worrying, is that the targeted ads on Facebook for ebay show something things I have been searching for, and some other seriously dodgy stuff, and just weird random stuff - barns, bitcoin mining stuff, etc. I guess that is based on my WAN IP address, as I don't see the same dodgy stuff when I use my Surface at work on the wifi there (thankfully!)

Sky avg downoad speed was 36.6 in Dec, but since switch to vf it has dropped to about 32Mbps according to SamKnows. Although the number of tests carried out on same days over the festive period was very low (more people in the house, so I guess more internet usage). For 2 days when I was at work this week the min test results showed 15.0 and 13.1Mbps, but also a max of 37.2Mbps on the same days, so pretty variable. On those days I was here pretty much only to sleep - no real internet use other than my phone checking for emails, etc. Certainly no large ISO downloads or streaming of TV programs.

You can tell the speedtester to user other servers.

I've spoken to vf, and they state that when you sign up and they give you guaranteed minimum speed (in my case 35Mbps) is for a multi-threaded download and not for a single thread. Obviously they don't go into that detail on the phone at sign up time, and they never sent me my confirmation / cooling off letter, so I can't check the finer print in that either.

Performance seems very variable, some minutes it is fine, others dog slow.

My SamKnows box has logged max speeds as low as 13Mbps (when there has been no one in the house), but other days up to ~36.

vf tech support don't seem to understand the difference between wired and wifi connections, as one lady I spoke to believed that splitting the wifi channels was going to help issues with my wired PC.
