Why do you only get about 10% of ISP Broadband speed?

    OK this is probably a basic question, I have googled it to death and cannot find an explanation.. Lets use a 1Meg connection as an example....

    So, your on 1meg broadband - why are downloads at roughly 10%.. you get about 100kbps download... Why cant you download at 1mb per second? I kinda know it something to do with bits and bytes and so on but I really need someone to explain it to me in really easy to understand terms. Its buggin me that I cant get my head around it.

    Replys much appreciated :thumbsup:

    Lots of factors affect the speed you get. Have a read of this:

    I'm on a 4mb link, but because I've got a high contention ratio, and because I'm quite far from my nearest exchange, the best download speed I get is about 1.5mbps, and upload is about 400kbps...

    the ISP's advertise the speed in megabits per second where as you see download speeds as megabytes/kilobytes per second/

    meaning that a 1megabits connection which the ISP advertise will give you a max of 128kb/s download a 2meg would give you roughly 250kb/s and so on. Though if your on ADSL you won't likely get this unless you have a good line and are very near the exchange. Cable should give you near the max though

    And your not going to be able to get speeds of 1.5mbps with a 4mb line!

    Whats confuses most people is that ISPs use the line rate whereas most software like Internet Explorer etc use transfer rate (as already mentioned & shown above by wormvortex1337) but then there is also the units used. Big B = Byte. small b = bit.

    So 100kB/s is actually 8 times faster than 100kb/s. Your average joe is not going to know that & even the ISPs & software programmers sometimes get it wrong, so what chance do the rest of us have!

    Ive thanked everyone in the thread! Great replys and info but wormvortex gets the gold star!! with Rygar a close second! LOL I understand! At last! Thanks so much guys. It does seem that its all about the ISP advertising bits and everything we do online showing in Bytes, thats where the confusion comes in. So if I look at my own cable connection of 4meg, then it now makes sence that i see maximum download speeds of around 480kBps (give ot take). So thats pretty much spot on...

    I just upgraded to 20meg with Virgin, waitin for a new modem but already im seeing about 1300kBps download rates so when i get the new modem and im not being throttled etc I should be looking for a download speed of about 2000kBps then.

    Its nice to understand, thanks for explaining.:hiya::thumbsup::thumbsup:
