    Hi Paula,

    When both rows and columns are added then Phase 1 of the simplex algorithm has to be executed and a non-standard warm-start is performed in this phase. This may be better than performing the calculations sequentially but is not expected in general.
    We would recommend to test whether adding rows and columns separately instead of simultaneously provides better performance.

    Best regards,
    Jaromił
