I’ve been noticing this too … But my update time is much faster compared to others around here, taking about maybe 12-40 seconds. But, I have seen a minute over the time …

Funny thing is, I still use Dial-Up occasionally, and it is fast there (keeping its original update speed). Also, my update might be faster because I don’t have my DSL network connected at start-up, I connect it later when I need Internet. Maybe if its at start-up, the start-up processes slow down the update progress.
