Maybe the UNION is trying to resolve duplicates that it doesn't have to??? i.e. requiring a sort

Have you tried UNION ALL

If I use a count(*) operation (in sqlplus) on the view that is the union (or the individual view), I run out of temp space e.g. ORA-01652: unable to extend temp segment by 256 in tablespace TEMP (108M temp space, ). If I do subsets, selects, whatever, the views are fairly quick with no problems-- I just can't perform count(*) operations
