There's something wrong with that arithmetic. Either that, or "over 4 hrs"
is a gross understatement, like saying a Boeing 747 weighs over 200 lbs and
can fly faster than 30 mph carrying more than 10 people.
Barring arithmetic errors of my own:
1GB in ~4 hrs ~= 256MB/hr ~= 72KB/s ~= 575Kb/s
15Kb/s would take ~150 hrs to download 1 GB.
The main reason Xcode updates are so friggin' big is because they're not
updates, per se. That is, they're not deltas relative to prior Xcode
releases.
Each Xcode release is a complete replacement for the entire Xcode and
/Developer directory tree that came before it.
