Major difference in single threaded speedtests


[link to this post]
 
So on TBBs single thread i get around 150-180mbps but on speedtest.net i get 480mbps

what would cause such a huge difference?

Speedtest.net defaults to multi-threading. Simples.

On most devices you can change it to single thread, just under or to the side of the large GO button. See what that gives.

Edit: Oops, I hadn�t noticed your actual tbb graphic. What�s the problem, other than the tbb multithread is faster than the other. Suggesting the other may have a server capacity problem.

Your links to Speedtest.net in your sig just take us to do a test, not to your results.

Connection - Three 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up.

The OP shows a speedtest.net single thread at 494/498 Mbps and Multi at 512/539 the little arrows confirm it red/green single, blue/purple multi

When I clicked they took me to results.

As MHC says, the Speedtest.net data looks good.

The question is really if Vodafone have a similar problem as Virgin Media had, with congestion on their link to Thinkbroadband. The Thinkbroadband test is WAY down in speed.

147 and 268 versus 400+ on speedtest.net

Noticed the ookla test is to a vodafone server so probably stayed on net, where as leaving network there are issues

Is our network contending, nothing visible and network monitoring would alert well ahead of nodes hitting the actual limit

Probably down to your location. I'm also in North Scotland (Inverness) and have never seen single thread speeds on TBB tester match multi on three different FTTP 330 lines (FluidOne, Trunk Networks & BT Business). Yet my single & multi-thread speeds are identical on almost every speedtest.net server. So you're not alone smile (and nothing to be concerned about IMHO)

Ummm. I don�t know why I didn�t get to those results before. Probably finger trouble this end frown.

I wonder what happens if he uses a non-Vodafone server elsewhere in the country.

Yes, I've seen over 1000 Mbps, from a corporate connection to your server, so suspected any issues wouldn't be on your network. As you detailed extensively for the VM issues a year or so ago smile

Yes. As just explained to MHC, I seem to have had finger trouble.

But the tbb graphic shows the multi-threading giving what I would expect from a 500Mbps sync speed. With user-end buffering causing the above 500 peak reading.

Can you post single thread results from the Xilo Speedtest.net server? If ok, then nothing wrong with your connection as that�s a pretty reliable ookla server.

Yep multi as well! Personally I find Vodafone London and xilo�s the most reliable ookla servers.

Another factor is that by showing the median figure our figures are sensitive to variations, and on watching various ookla Gigabit connection tests the speeds seem to ramp up as test goes on and final figure is what is reported, rather than any average. Good for boasting but of little use in seeing if there is a dip in speed.

I suspect this feature will become more and more important as speeds go up, and variability increases.

I don't think most UK consumers would cope with my friends in US cable service. You get 350 Mbps or faster in the middle of the day, but 30 to 50 Mbps in the evenings!

and one TBB i've just used

my main question is where would i encounter this single threaded speed in realworld apps? as i've not seen anything under 55MB/s when i download from browser or steam or whatever else.

So your single thread results on the Xilo Speedtest.net server tally with the Vodafone results, both of which are considerably higher than the TBB results. This clearly suggests the tbb single thread results are inaccurate so you�ve probably got nothing to worry about.

Networks are getting insanely complicated. Due to the increasing speeds.

I don't know how these things are set up, but I wonder if the tbb single-stream test is routing down a lower speed link at their end than the multi-stream.

Of note from the Vodafone Gigafast is that there seems to be a pattern of high start with a fade over time.

Do you have any TBB results from North Scotland on the higher end (>200Mbs) services? Though I imagine there won�t be a huge number of users in this bracket!

I wanted to know what folks were getting on the single thread TBB tester on 330 & above FTTP services in the Highlands. However you seem to be on FTTP 80/20 and your single thread TBB result looks fine. Mine doesn�t:
