Oracle 8.0.5 - Partition index performance

We are considering using the partition feature for the major objects in a DSS database, primarily for maintenance reasons in order to purge and archive data each month. Since the partition key will be month, and most of the queries use data in the predicate, this should provide some performance benefits too. I am concerned about performance for queries which do not use the date, and will be forced to scan local indexes for each partition - this is fortunately a low percentage of the query load, but I would hate to have this queries run with extremely poor performance. Does anyone have any benchmarked or observed performance for this type of situation?
