Two questions...
1- Are tables partitioned by v_column_name ?
If yes... truncating or switching partitions are good options to take into consideration.
2- What's the percentage of rows being deleted?
A high percentage purge works faster doing a reverse purge, instead of deleting what you don't want anymore, bulk insert what you want in a new incarnation of the same table.
