It took only 8.5 seconds for half the subjects to either walk out or hit the reboot switch. Switching to a watch cursor during the wait delayed the subject's departure for about 20 seconds. An animated watch cursor was good for over a minute, and a progress bar would keep them waiting until the Second Coming.Also cited in Speed Up Your Site: Web Site Optimization.
