WordPress MU

time during upgrade blog with latest mu version.
60 blogs eg: wpmu-upgrade-site.php?action=upgrade&n=60
almost 56sec to upgrade 5 blogs, since I'm using lousy server. :(

how about thousand blogs upgrade?
if line disconnect will cause any happen?

I think it took me less then 10 minutes to update 1300+ blogs, and I am on a shared account.

I've pontificated over this for a while: http://mu.wordpress.org/forums/topic.php?id=2070&replies=22

i mentionned my own experience here:

about 1 sec / blog, although i've never run the online upgrade but had a command line script made.

10 minutes sounds right for that many blogs.
