New install speed query

After years an extremely long wait with my cab being missed it has finally gone live during an infill and I was connected yesterday!

I am approx 500 meters from the cab and seem to be getting good sync speeds.
I have unlocked the modem and sync speeds are pretty constant at :

# xdslcmd info --state
xdslcmd: ADSL driver and PHY status
Status: Showtime
Retrain Reason: 0
Max: Upstream rate = 24844 Kbps, Downstream rate = 73040 Kbps
Path: 0, Upstream rate = 20000 Kbps, Downstream rate = 72139 Kbps

I do have a query with throughput though!

If I run a test on this site I get an extremely poor 5mb download but ~ 17mb upload.

On speedtest.net I am showing approx 18 - 25mb download and again ~ 15 - 17mb upload.

I have tried some real world tests from a variety of places (including DChosted servers that I have access to) and can not get any more than approx 20mb of througput even multithreading downloads from different places and types.

Also ping response seems a bit hit and miss with the odd timeouts even to early hops.

Is this likely to just be congestion in the local network?

Please can you run the BT speed test and post the contents of the two results text boxes.

Which ISP are you with?

What about the BT Beta speedtester? http://speedtest.btcentralplus.com/beta/

What does the graph in Task Manager - Networking Tab look like? Can you run the three tests and then post a link to a screen shot?

Are you connecting via wireless or wired?

I am now with BT with the up to 80/20 infinity 2 product.

Speed test from the tester you link gives :

0 Mbps 69.83 Mbps
Max Achievable Speed

Download speedachieved during the test was - 30.08 Mbps
For your connection, the acceptable range of speedsis 12 Mbps-69.83 Mbps .

speedtest.net & real world tests are ~ 20 Mbps down when done just after test.

task manger is showing very little network utilisation (on gig connection)

I am wired, I do not beleive it to be a local issue.

The 5Mb test from this site and the ~ 20Mb tests from speedtest.net were initially done with the new install, modem > homehub > laptop (high spec) with wired connection to the gig port on the home hub.

Network was gig/full

Since then I have connected to the rest of my network.

The homehub has been replaced with a Cisco 871 and tests now performed from a desktop machine.

Desktop > gig switch > (unnamed gig capable firewall) > Cisco 871 > Modem

Results are identical.

I have also disconnected and again tested with homehub & hardwired laptop and exactly the same results!

It does not matter whether you have a 100Mb, 1Gb, or 10Gb network card. If you run just those three speedtests it will scale and show the pattern of what is happening.

I can get a screenshot later, it was not a very interesting peak going up to a few percent.

87x series struggle with FTTC over 15-20Mbps.
You'll need an 1800 or 880 series to get up to the 40Mbps mark at least.

Do a show proc cpu hist and you'll see why.

Doesn't explain why you're getting low results using the HH though.

FYI: http://forums.thinkbroadband.com/fibre/t/4134882-slo...

That's my experience. I graphed the results from Speedtest.net this morning and it's very clear. Between 9th May and 17th June results vary between 50Mb/s and 60Mb/s. After that (last week and a bit) they are all over the place but the bulk lies between 30Mb/s and 40Mb/s.

I haven't unlocked my modem yet but my profile remains at 76.76Mb/s.

Very similar to what I've been getting. Whereabouts are you? I'm in Brackley.

FWIW I've got nowhere trying to talk to my ISP. Basically if it's within that range it seems we just have to suck it up and live with it.

Edit:I see that you're in Luton. Not likely to be the same node then I wouldn't think. We hang off Birmingham last I heard. Although...hmm. My latency dropped at the same time last week as well. What latency do you get to London/Namesco according to Speedtest.net? I wonder if my routing changed from Birmingham to Milton Keynes? That might reduce latency and put us both on the same node. Dunno if that's even possible.

At the risk of "teaching granny to suck eggs"!

You may have already done this in which case I would be interested in the results!

Have you tried streaming video to another PC ( or PCs) and then running the speedtest. If the speed remains the same this would indicate that it is not the line/connection but may be a PC issue or a router somewhere that is limiting individual streams to (below) a set value.( Same effect as contention but constant over time).

I believe that some of the speedtest issues on high speed connections are due to PCs abilities or configuration settings on PC's and across the network restricting individual PCs speeds. Some connections seem to be able to run 2 PCs both at the same speed as one PC.

We will see even more of these issues as people move to 330Mb. I think it is unlikely to affect most people's real world performance but will be visible when people use speed testers across the Internet.

I'm not sure what you mean by that. I have a server in my house and PC to Server transfers are way above what even FTTC is capable of so I don't think it's my PC or router causing the issue.

Also there was a very definite speed drop as witnessed by the following speedtest.net results:

6/20/2012 9:11 PM,GMT,39.6,9.14,13,London,250

Also note the latency change (second highlighted column)

I understand the limitations of the 8xx routers and had allready checked the processor (and am mappting the processor utilisation via prtg) as well as checking it live when running the tests.

I have a minimal configuration currently, basic pppoe, nat etc and have not seen the processor above 50% at any point during the tests.

The speeds were also the same during install using laptop directly to the homehub and I have gone back to this to retest since

thanks for the suggestion though!

Gary

Hi,,

Yes I am in Luton
Currently showing 16ms to the London Namesco test server on speedtest.

We would need a traceroute to see if our routes converge at some point.
I am guessing there is some major oversubscription somwhere.

At least I am still running far quicker than I used to!

I'm kicking off one of those this evening. I'm not sure if it would show all the hops though. It could be the BTw/BTor routing that has changed rather than the 'customer visible' IP routing.

At least I am still running far quicker than I used to!

Me too and in fact my minimum speed is 1Mb/s faster than I got with Bethere

I've run some traceroutes and I'm seeing high levels of packet loss. Intriguingly I'm seeing 30% on the first hop into IDNet's network then a further 5% on the next hop. The first one could be down to BT's network I assume but the second one is presumably all down to IDNet. Either way it adds up to around 34% for almost every location I put in.

As I read him he means have two, or even three PCs connected to the router, with one or two of them streaming direct from somewhere out there. Nothing to do with your inhouse server or LAN. Then do the speed tests on the remaining machine and see if they stay the same, or fall off due to the others using bandwidth.

Just out of interest, what does this test make of your connection ?

It looks like all machines are sharing the same bandwidth to me.

Showing 42/14 on that test.

Also showing the same speed this morning on speedtest.net and also the same on the test on this site.
Something has changed as on this site I was only showing 5mb on every test.

my line also reset this morning

# xdslcmd info --state

Interleaving depth is now showing @ > 1000 and ping response to the early BT hops has gone from 6ms to 15ms

Why and where is te proof?

It is rated as a fast Ethernet device with 100Mb capability so should work without issues. And why with FTTC - it does not know what service it is connected to as the WAN input is a 100Mbps Ethernet.

Just because the ports are 100mb on the router doesn't mean it has the grunt to fill the line.

A lot will depend on how complex the config is / what you are asking it to do.
With my tests this morning I am now getting ~ 42mb after my line reset this morning and the router processor is hitting approx 80%

Nothing changed here on this site.

I was unable to unlock my modem this morning. No idea why. I followed the instructions, the router rebooted and it was still locked.

Can you run some continuous trace routes? I'm seeing 20% to 30% packet loss on the first router outside my network (which is one that belongs to my ISP).

The router rebooted?

In reply to a post by RobertoS:

The router rebooted?

Lol, my mistake. Still had Garry's message in mind. No it was the modem rebooted.

Everything looks good now:

Even TBB is looking good apart from the infamous upload figure:


..best downstream ever from TBB. 1GB test file comes in at 7.8MB/s. Quite shocking in one respect - I could burn through my peak allowance for the month in 15 minutes. Good job peak time doesn't start until 9am

forgot some people still have to suffer download allowances
