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 :

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 .
Additional Information:

2. Upstream Test: -provides background information.

Upload Speed
11.8 Mbps

0 Mbps 20 Mbps
Max Achievable Speed

Upload speed achieved during the test was - 11.8Mbps

10.58Mbps Upload

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.
