1) Load Data using Bulk Load for that we have to drop index from the target table, but after loading the data to create the index will also take good amount of time
2) Create a sequence 1 to 100 million using sequence generator and create the pass-through partition to load data, let say 10 partition we can create from 1 to 100000 like that.

Partitioning will definitely give huge performance improvement.
