Debugging shows that the problem is in 'isearch-update' where the call to 'pos-visible-in-window-group-p' doesn't return. When this call is removed, the search is instantaneous. (Optimizing lazy-highlight is a separate problem in bug#56815.) The problem is that pos-visible-in-window-p starts from window-start point and goes to the POSITION passed as argument using move_it_to, which in this case is very slow, because it has all the 10000000 columns to traverse. The solution is to introduce shortcuts into pos_visible_p in this case.
