Disable indexes and triggers, lock table (may be faster)

Disable indexes and triggers during the import. Note that if you selected this option, it might lead to a situation when a trigger does not fire and fails to pass its results. Though it might improve the performance of the importing process. The option is available only when the target table (to which you copy values) has indexes or triggers.
