You got the command a little bit wrong. It should read:
$ sudo apt-get update && sudo apt-get dist-upgrade
The dist-upgrade option only makes sense when you have changed the repository sources to the newer release of Xubuntu.

Update contacts the servers configured in your repository list (Files in /etc/apt/apt.conf) and looks whether any new packages or newer versions are available. It updates the file
'/var/lib/dpkg/status' with the package lists found on the servers. That is important since apt will only let you search for and install new packages when it can find them in the local file.
Have a look at:
$ view /var/lib/dpkg/status
You will see that a lot of packages are listed along with their version number and the
installation status, i.e. whether it is installed or not.

I don't know why takes so long. When I was using Debian Unstable (Siduction is based upon it) that didn't take my computer so much time,even if there are new package versions added everyday. Sorry, can't help you here.
