Why are broadband speed tests results so different?


[link to this post]
 
I just upgraded my broadband connection and wanted to see what I was getting. I googled "speed test" and checked the speed with the top three website results:-

www.speedtest.net - 13.52 Mbps download and 15.07 Mbps upload
www.broadbandspeedchecker.co.uk - 5.58 Mbps download and 7.69 Mbps upload
www.thinkbroadband.com - 4.85 Mbps download and 15.44 Mbps upload

There doesn't seem to be any consistency?

I suppose it depends on how congested the route is between you and the test site at the time of the speed test.

On ADSL you could guestimate 85% of your sync as the best speed you will get.

Is there one you use that you feel is accurate/consistent?

thanks

Try the Maidstone server on speedtest.net ... at least that is connected to a data centre with a 10Gbit backhaul. Others often only have 1Gbit or less and become congested very quickly as it seems doing speedtests is an every day activity for some people!

Afraid not. Don't worry about speed tests as they rarely indicate the speeds I'll get from the sites I'm actually using.

Different testers use different methodologies e.g. the ookla based ones tend to show the peak speed, where as ours tends towards showing what speed you will get from a sustained non-HTTP download.

Server speedtests are useless for measuring speed of your local network. You need to write your own to run between your devices.

Best way to test your speed is load up a well seeded torrent, run a few http downloads and monitor your bandwidth activity through a program such as Networx or TbbMeter. You should then see a filled green graph going at pretty much a straight line, and you can get your max download speed from that.

a good program is Jack Dinns Auto SpeedTester, load it up, set it to 58 minutes & leave it to chug through the day. You will then get a chart that shows your speeds throughout the day & an average.

You can also change the site & size of the file you download, depending upon any limits imposed on your connection.

Being on VM30 7Gb am 3.5 afternoon & 1.5 evenings, lets me use some of the larger files, you need these to get a decent reading & the download completes before the true speed is reached.
