I have found that updating a mirror takes on the order of 10 minutes. 
They are setup by default to update on the hour, so, I update at some 
point after 15 minutes after the hour. I move my mirror update until I 
quit getting busy timeouts. I am updating at 30 minutes after now 
simply because it is a convenient number :). Watching cvs-all and my 
updates, my mirror gets code that was modified ~10 minutes before the 
hour, which is when the mirrors update.  Cvsup isn't that far behind if 
you wait for your mirror to update. If you are patient, you are only 
1:10 behind at the most. Just don't update before 10-15 minutes after 
the hour and updating more than once an hour doesn't normally 
accomplish anything. You just consume more bandwidth needlessly.
