So as long as I've been playing Skyrim (installed on HD on a 250 gig Xbox slim FWIW), just bringing up the save or load game menu has taken 30 seconds or more, but when playing or loading saves on other 360 consoles (even my friend's old school 360), or from the cloud, the menu pops up immediately and saving or loading is much faster.

Anyone else have this issue or know what causes it?
