    Enabling the Contraints in Database taking more time compare with disabling the constraints. What would be the reason.

    Disable operation Just disables the contraints and It doesn't need to check for its validity.

    But when you enable it again It has to ensure that all the data present it tables holds good against the corresponding constraint. It will try validating the constraint for each and every record.
