Mine was much slower than usual. It took about 16 minutes, I usually do the same in much less time. My download was running at about .4 Mb/sec in contrast to my usual 1.6 Mb/sec. I'm not sure if I can put Apple, or my cable connection to blame, but it was frustrating when the update took twice as long as I expected when I needed to be somewhere at the time... Oh well, who gives.
