The nice people at 'Virgin' have upped my download speed to 10M bits/sec so I thought I would download the 64bit version of Windows 7100, all went well for about half an hour but then the rate dropped down to 250K bits/sec.

* subject to fair use

A common trick of the broadband companies is to throttle your speed if you use too much data. Sounds like a case of that.

Just like the proverbial banks really: anxious to lend you an umbrella, but demand it back the instant it looks like rain.  >:(

Wow, 10M bit/sec! My normal broadband speed is 250 K bits/sec!

I used to get about 5.6Mbps real throughput on my "8Mbps" linespeed when I had ADSL in my previous place. Now I rely on 3G mobile broadband and get 1.5Mbps sustained throughput on a good day, but web-page viewing often gets slowed down by the telecos kit reasons unknown. ???
This particularly seems to affect InVision Powerboard -driven forums such as this one, when, on a bad day, after clicking a link it can take 1-2minutes "doing nothing" before the page appears. >:(

Yes, usually it says at the bottom, page created in 0.030 seconds or something like that, the other day it was: page created in 52.260 seconds!

I can't understand how the ASA (Advertising Standards Agency) let these suppliers get away with adverts saying 'unlimited downloads' in large print, then 'subject to fair use' in the small print. Its either unlimited or its limited, it can't be both!

The definition of 'fair use' usually involves you not continuously using the link for more than 1/50 or 1/20 of the time you're logged on or something- almost all broadband services you can buy are 'contended services'; or what amounts to that (e.g. no limit but they'll slow you down or charge you more if you download or upload more than a certain amount in any given time).

You can often buy true unlimited business quality service, but it's usually 10x more expensive or something.

I totally agree.
And at least one well-known broadband supplier in the UK (with an Italian name and rather poor recent financials) point blank refuses ever to define what their 'fair use policy' is, yet operate a three-strikes-and-you're-out approach.

Blame 'marketing'.



By the way DO NOT CLICK on the MalwareRemovalBot advert if you see it on this page. It appears to be peddling software of very dubious origins (FAKE / SCAM anti-virus/anti-malware).

I switched to a business broadband service (from domestic previously) and the speed, stability and reliability are a whole different ball game. The upload speed is 5x what I had before, the download speed is roughly double. Moreover, the stability is the real winner. Now I know that when I fire up a download it will complete at a stable rate. The reason, of course, is that the number of people sharing my business connection at the exchange is probably in single figures (because of where I live). Poor old domestic users, on the other hand, probably outnumber me manyfold to one...

Ironically, the business rate is cheaper than the domestic rate too!

normally broadband doesn't depends on the OS much.. It depends on the memory you are using..

Can I just point out something here.

I saw someone measuring their internet in KB/S and others in Mb/S

250KB/S = 2.5Mb/S

This is because ISPs try to trick the average user into thinking they are paying for a faster service, they measure in megabits rather than megabytes.

Therefor to truly get 1 megabyte a second you would need a 10 megabit connection.

Its a cruel trick that isn't illegal as they are measuring it correctly just using a different unit, it would be like using decimeters to measure length to make something sound bigger.

Anyway, some ISPs use give you very fast burst to begin with, i forget the technical term, basically it means it gives you your full speed for a short period of time, i think about 30 seconds, this is for small files that they aren't worried about you downloading but if your download continues then it slows down to stop you hogging bandwidth.

I on the other hand have rubbish speed so it starts slow and gets faster then slows down again, I dont know why this happens but Ive noticed a lot.

When the actual speed (as opposed to the advertised or published speed) of your broadband connection varies, this indicates that you're using a service which is non-dedicated or shared. The connection speed of a dedicated connection is constant, and as such, is relatively expensive for the average non-business consumer. The performance of a non-dedicated or shared connections is impacted by the usage of neighboring service subscribers and this fact is a huge factor as to why broadband users see variances in network throughput or speeds.

Also, the standard unit of measure for telecommunication circuits speeds is always, Megabits per second, or Mbps. The only "trick" is awareness, and the knowledge that a byte is generated as a result of the receiving 8 or more bits, depending of the mode of transmission.

10Mbs to .25Mbs that is a huge spanking...

Regarding a DSL user, I have heard of multiple movie downloads continuously on 3Mbs took a little time but there was no ISP throttling conflicts.
10 Mbs download speed is almost real time in internet time, you should beable to watch movies
DVD size
An opsys should should be smaller than a 640 meg CD, that download should not have taken that long at 10 Mbs.
I could see the speed trottled back by half 5 meg or 3 quarters 250 meg but to kill your speed to kilobits/s that is not right or I should say there some mistake on their part?
That is like Snail mailing you a stamp and an envelope with instruction how to  get your information by snail mail.
