Re: constraints and performance

They would be expected to provide a significant enhancement to
performance over:
 a) Firing triggers,
 b) Firing rules, and
 c) Forcing the application to validate the data, and then adding
    in "data validation" reports to report on the cases where a buggy
    application violated the constraints.

So yes, they should be considerably faster than any of their
alternatives.
