There has to be some criteria you can use to reduce the partition size.

We know inserts with a partition present take longer. This is proven. I'm suggesting you find a way to avoid inserting into the index, like direct path load into a separate table, build the index, then use exchange partition to swap it into the large partitioned table. Many people have saved enormous amounts of time with a scheme like this.
