Want to vary the number of regsitrations, messages and matches and measure the corresponding variance in execution time.
Each registration will contain the 'All' header, even registrations will contain the 'Even' header and odd headers will contain the 'Odd' header. In additions each regsitration will have a unique value for the 'Specific' header as well.
Messages can then be routed to all registrations, to even- or odd- registrations or to a specific registration.
