UNDO_RETENTION specifies for how many seconds undo information is kept. The default is 900 seconds and you can set this parameter to guarantee that Oracle keeps undo logs for extended periods of time. By example this parameter specify how long undo information should be retained after commit, preventing "snapshot too old" errors on long running queries in addition to supporting Oracle flashback query.This could be the reason for your slow performance with multiple inserts.
Revert it back to normal after your insert operation.
