I have found the copy command to be somewhat slow. I would either create a pl/sql procedure to perform the insert (allowing commits), or dropping the table (since you are truncating anyway), running a 'create table as select' statement, then rebuilding the indexes. I find this is usually the quickest way to drag data across a database link (assuming you have the tempspace to do it). It you use the 'nologging' clause, it will also avoid redo activity.
