Hidden download performance problem with Fedora 6-10

I have not used Fedora because of the following issue.
I get VERY SLOW performance or hangs when downloading from repositories
etc. on every Fedora version I have tried. I have seen users raising
this issue since Fedora Core 4. So I can't use Fedora; but would like
to. I apologize for the length of the message. I have tried the Forum
but got no help there.
To investigate, I did manage to get wget downloaded and installed while
running from the F10 live CD. ( I won't bother installing any Fedora
until this issue is fixed. ) It took way too long to accomplish but wget
did eventually get installed.
I used wget in a terminal window to expose what is going on. So from
the live CD I mounted an existing ext3 partition and went to its temp
directory. Then I launched wget to download again the F10 live CD ISO.
Terminal output pasted below between the dashed lines. Note the data
errors, retries and eta of over 46 hours at one point...

So, is it the mirror? or Fedora? So I attempted to download the Ubuntu
8.10 release with the same setup...

So, the problem is with Fedora. ( I have run many distros on this
hardware and Fedora is the only one with this issue. )
To demonstrate, I took out the CD and rebooted into Debian Lenny which I
am now running. I decided to wget the Fedora iso again..

Non-stop. Just over an hour duration. Full speed and ON THE VERY SAME
HARDWARE.
So it is not the repositories which so many people want to claim ("It's
just busy")
Others have noticed the same general performance problem without getting
any useful assistance. ( EG told to "tweak firefox settings...")
I would like to assist in solving this. I assume it affects many
systems but the users are just too willing to accept the slow
performance. Using a GUI hides the actual issue. Other users have just
droped Fedora and returned to some other distro. In my case, the errors
and "connection reset by peer" things completely hamper my ability to
install or upgrade software. It truly amazes me that I got the wget
downloaded. The differences in the examples above should make someone
take notice.
I am done now.
Thanks,
charlie
