performance: because the are physically split like their corresponding table, so the engine will only use the part needed by the query
I'm in agreement IF queries are hitting a single partition; for queries retrieving data from a large number of partitions this actually increases overhead. Remember, table-partitions and index-partitions are nothing but collections of physical tables and indexes, not the same to hit one table and one index than to hin n-tables and n-indexes to fullfil a query.
