Just a stab in the dark, Is the second path sorted? If so, is the sort item
near the front of the record? Has anything changed about the values being put
in the sort item (or any item after it? The second path looks to have long
chains (340 records avg per chain) and sort items might be hampering the
performance. (I wouldn't guess that 10 minutes would be the order of the delay,
though).
