Hi Kevin,

Walter mentioned this but only indirectly. . .

*IF* you are running with DELETED ON *and* your tables (especially the ones used by the views in this case) have an index/TAG on DELETED() *and* the proportion of actually deleted rows is either very very low or very very high
. . . this would most likely be your problem.

The "cure" for the above case is to eliminated the TAG on DELETED(). While this will give only partial optimization, that is better in this case than full optimization.

Good luck,

Jim N
