    Your ISP must over provision so as in congestion/peak time, customers will still get advertised speed.

    My ISP does the same.

     

     

    Mine too. (Virgin Media UK)  I get significantly over the advertised speed even in congested times.  My headline speed is 300Mb, but I now get 331Mb consistently.

  2. Take a look at this discussion here  Home Networking

     

    The difference between speed test and another is pretty profound. It works like this (not very technical and skips over a tonne of technical aspects, but it demonstrates the issue at hand).

    If you imagine 2 users, call them Bob and Mike.

    There is 100Mbps split between the two of them at the local exchange, node or street box.

    Bob downloads a file (1 threaded), he gets 100Mbps.
    Now Mike runs a speedtest, single threaded. Bobs download slows to 50Mbps, Mikes speedtest gets 50Mbps (sharing available backhaul).

    Say Mike runs a speedtest with 9 threads, Bobs 1 threaded download falls to 10Mbps, Mikes speedtest shows 90Mbps.

    With multi threaded speedtests, congestion is hidden a lot more.

    Hence ISPs send you to www.speedtest.net as it's multi threaded and very good at covering up congestion issues.

     

    Your ISP will try to use the multi-thread test as the standard against which they test any claim that you are not getting the download you pay for. 

     

    Congestion in your local network could easily affect the outcome of your single-thread test depending on the architecture of your network. If you are lucky you will have a single coax or a twisted pair copper line  all to yourself. straight from your local street box. This would give you no local congestion, but the same issues as anybody else when negotiating the wider network, much of which has nothing to do with your ISP.  If you are a cable user, more likely you are sharing a coax with other users giving you local congestion on top of everything else. 

     

    To test your speed you might also use a really fast file download site,  e.g Visual studio  Try two or three files at the same time then  add the download speed of them all to get the maximum.  ( Windows show speeds using MB rather than Mb. Just multiply the MB result by 8 to give Mb. )

     

    When fighting this out with your ISP they always have the get out that the download speed they quote to you when you buy in to their contract is an 'up to' speed. e.g. 'Up to 200Mb'. If you look at their small print they will cite congested times of day as possible causes of slow test results. They can also suggest that your home kit might be causing problems.

     

    The good thing is that unless you are experiencing poor service  e.g. problems with browsing, streaming, game play or downloading and up loading large files then you probably have nothing to complain about. Speed tests are not a good indicator of the service you are getting, but your daily experience as a user is.

     

    Only yesterday I was having trouble streaming from my own cloud (Livedrive) . I rang my ISP (Virgin Media - UK) and explained that even though my speed test gave me my usual >300Mb download speed and 20Mb up speed, my videos experiencing showing slow buffering. They tested my connect right down to my modem and found that power levels were too low on some of my channels. They adjusted this and put it right.

  3. Virgin Media are keeping to a 10:1 ratio for now, so I guess 120Mb download will result in 12Mb upload.

    Any news on the Euro test server?

    BTW here is my current line quality monitor (Live) . Quality is almost as important as speed when it comes to video streaming and gaming.

  4. Not been here for a while. I can't find the Euro test server option. Is that now defunct?

    BTW My connection is going up to 120Mb soon. Virgin Media are upgrading all UK cusomers for free. Most will be double speed, but those already on 100Mb will only be raised to 120Mb.

  5. Up and download speed are very important, but so is line quality. Who wants high latency and packet loss, especially if you are a game freak?

    For those of you interested here is a line quality monitor I have started with Thinkbroadband. This is live so it will change over time.

    I am pretty pleased with my line quality. Any spikes you see are due to my internet activity. The rest of the time all the graphs flat line.

  6. Well here are the results of a tracert and ping. To my untrained eye this doesn't look too bad. I don't see any obvious bottle necks.

    As you can see the NAMESCO server in London gives me my usual 97Mb. Rotterdam gives me something lower owing to distance I guess, but testmy.net has not done well.
