It happens when the computer has just been started.
Head into Safari - Preferences - General
Change the 'Safari opens with:" away from Opens all windows from last session.
Having that option selected and you had several windows/tabs open last session is going to give you the beachball quite often while all of those sites are loading - there is no stopping the beach ball in that circumstance if you had a bunch of sites open you want re-loaded.
