On speedtester my internet connection download speed is tested at (about ) 4.5MB/s.
When I recently downloaded a 12GB file the initial download speed was 5000 KB/s (good) but soon dropped down to an average of 588 KB/s (took over 7 hours!!)
Why is there such a difference in the actual DL speed.
Thank you.

Depends on soooo many things.
Local network usage.
How busy the server is you are downloading from.
What protocol you are using.
How fast your PCs HDD is.

Its impossible to say without a hell of a lot more info.

Thank you.
Only one user on the network.
Don't know how busy the server was at the time.
What protocol ?? don't know about that but if it helps I'm using BT internet with a home hub 4 and a wired connection.
Main HDD is a Seagate 7200

Best way to test this sort of thing to see if your line is performing as it should is by going to your ISPs site and checking if they have an FTP to test with. You can call them and ask.

BT have tested my line and as far as they are concerned it's all as it should be. Dealing with BT is not the easiest thing in the world!

Test it yourself.
Ask them for an FTP test on their site that will allow you to test throughput.

Thanks, I'll do that.
In the mean time are you saying that, with the info I've posted, I should be getting a much faster file download speed ?

Yes you should, but again, there are too many factors when downloading from an unknown site.
