Rebooting is necessary if there's a kernel update; it is recommended if shared libraries are modified, since that's the easiest way to make sure that you don't have any daemons which are still using the old libraries. Approximate run times... somewhere around 2-5 seconds plus download time; for a single advisory, the total time will probably be under 30 seconds, while a more significant update (say, 12 months of updates to FreeBSD 4.7, or the 5.2 -> 5.2.1 update) might be as much as 5 minutes. Connection speed is remarkably insignificant here -- FreeBSD Update uses binary diffs (why doesn't anyone else do this?) to reduce update sizes by a factor of 50, to the point where most of the time is spent on HTTP/TCP round trip times.
