The default setting is appropriate for most situations, and will give the best query performance.
IN-list rewrite processing precludes predicate simplification and block optimization during query processing. So in rare cases, using an IN-list rewrite for a query with an IN-list can result in a performance degradation, compared to processing without the rewrite. In these cases, you should increase the value of InListRewriteThreshold to a value greater than the number of values in the IN-list in the query.
