For those people who are having serious speed issues with up2date all you need to do is change your up2date sources file and add it a local mirror.
In your the /etc/sysconfig/rhn/sources file you may have the following line:
yum updates-released http://fedora.redhat.com/updates/released/fedora-core-1
Which if you open in a browser actually goes to:
So all you have to do is find a local mirror from here:
And then modify the /etc/sysconfig/rhn/sources file to add your local repository. To add a UK mirror listed as : http://www.mirror.ac.uk/sites/download.fedora.redhat.com/pub/fedora/linux/core/
Navigate the mirror in your browser and use the full URL which points to the i386 directory otherwise it isn't going to work. So the fhe etc/sysconfig/rhn/sources should now have the following entry:
yum updates-uk-release http://www.mirror.ac.uk/sites/download.fedora.redhat.com/pub/fedora/linux/core/updates/1/i386/
That should all be on one line.
If you comment out your old updates-released mirror, you should no longer have any speed issues with up2date.
Hope this helps,
