    // a single compute-intensive Payment.
    //
    // Timing was performed using a MacBook Pro laptop and a release build
    // with asserts off.  20 measurements were taken of each of the Payment
    // and TicketCreate transactions and averaged to get timings.
    //
    // For the example compute-intensive Payment a Discrepancy unit test
    // unit test Payment with 3 paths was chosen.  With all the latest
    // amendments enabled, that Payment::doApply() operation took, on
    // average, 1.25 ms.
    //
    // Using that same test set up creating 250 Tickets in a single
    // CreateTicket::doApply() in a unit test took, on average, 1.21 ms.
    //
    // So, for the moment, a single transaction creating 250 Tickets takes
    // about the same compute time as a single compute-intensive payment.
