If you have indexes on the table you may want to drop prior to delete and rebuild them after it completes.
Does this table have foreign key constraints?
Rowid is the fastest data access method.
Create a interim table of the rowids for the rows you want deleted and delete from table where rowid in interim table rowid column.
You may want to lock the table if you are worried about row migration.
