Mayby by christmas the 90MB of updates after a fresh install.Hip Hurray
Is it so slow every time?
Nope normally not... what version are you on at the moment and from what mirror are you downloading?
Perhaps you first need to consider updating yum (this is probably not at the latest version, considering the larfe amount of data for your update), With the latest version comes a fastestmirror plugin, maybe this will improve download speeds as it will probably find a faster mirror than the one you might be using at the moment.
