I had same thought as you. select into temp table only took a minute, then
insert into contact took 1 hour. Thanks!

So, how long does the just the select take? You might be running into
something odd with selecting from and inserting into the same table: I'm
not sure of the visibility rules here. You might be better off selecting
into a new temp table (see: SELECT INTO) then inserting from that.
