I don't think that site you linked to is providing the bandwidth needed...

To be more precise, would that be possible to adopt few more steps to get a more clear picture.
1. download bandwidth monitor from below site trial/free version.
http://www.paessler.com/bandwidth_monitor
Install the network monitor for localhost.
2. Download wget for windows from below its an open source tool from sourceforge.
http://gnuwin32.sourceforge.net/packages/wget.htm
select the windows version, download & install.
3. after installing wget for windows, open dos windows & type following on dos command to add path for wget to work in dos window & this change is temporary, when you restart your windows, path statement will be reset to default.
set path=C:\PROGRA~1\GnuWin32\bin;%PATH%
copy past above line into dos window
4. create a temp directory for download, such as abc, you must have atleast 10GB approx space free because it is going to download whole DVD source of approx 4.7+ data size, just for safe side, when test is finished, you can just delete it.
5. switch to newly created directory, in my case I will create a directory abc
6. before you kick start download test, you must check one message on the source server that I would like you to read carefully, it is about speed.
To check current load level on heanet nodes, go to following url using browser, you can also check connection stat & aggregate traffic. click on both links one by one to see in more details there are graphs for more options.
http://ftp.heanet.ie/
type following in dos window
ftp ftp.heanet.ie
when you press enter following below message will be displayed, just for your ref:
Connected to ftp.heanet.ie.
220-
220-Welcome to the HEAnet mirror site, ftp.heanet.ie

220- please disconnect now.

220- Irish National Research and Education Network.

220 FTP server on ftp.heanet.ie
User (ftp.heanet.ie

none)):
when you type following on dos window inside that newly created temp folder for test
ftp ftp.heanet.ie
the above ref: message will be displayed, just press enter to get out of that message, you will be prompted with ftp prompt, just type following below on ftp prompt to exit from ftp prompt than press enter to exit back to dos command window.
bye
press ent & you will be back on windows.
7. now we have to visit one more url it is hosted on heanet.ie servers to see what you are downloading for test. site address is given below.
http://ftp.heanet.ie/mirrors/centos/5.4/os/x86_64/
above url is for CentOS entire DVD 4.7GB+ in size.
8. plz disable all firewall & antivirus software for the time being so PC is fully dedicated to this process, plz do not do any other web related activity in 1st test, in 2nd test, use internet for email & browsing to add the stress, go to google, yahoo & msn etc. Do your normal stuff while doing the download as well, side by side keep an eye on network monitor as well to see your utilisation level.
9. Now start the download process in that dos windows, I am assuming that you have already installed & set the monitoring of localhost bandwidth usage.
wget -r
http://ftp.heanet.ie/mirrors/centos/5.4/os/x86_64/
-r switch will recursively download all folder & sub folder in the tree
You will see a lot of activity in that dos window, just don't worry open windows explorer & start checking size of that temporary folder after 5 to 10 minutes, to see if the size is growing & in the mean while open network monitoring tool to see live bandwidth utilisation.
Why I am telling this bit complicated process, because, the uni servers are in pear mode feeding to heanet servers, there speed is the same as of heanet, but because I have no other way to prove it, I have to request this more detailed process to confirm the speed of the backbones.
I also want to make it clear that I am not associated with heanet in any case, I am just a one ordinay sysadmin in a company based in london. so I have to download these stuff to keep company linux & windows servers.
WGET is a site replication tool, plz use it wisely, or you can get a letter from your ISP for excessive usage.
heanet backbone is one of the three biggest edu backbones in UK & IE
Plz share your result after test for at-least twice, I mean both tests.
After test plz make sure that you don't forget to enable your firewall & antivirus.
Regards.
