Hello,  
As I understood, your research show dependency between solver and calculation time. And I see in research [Implementation of the CUDA Cusp and CHOLMOD Solvers in CalculiX](https://calculix.discourse.group/t/implementation-of-the-cuda-cusp-and-cholmod-solvers-in-calculix/240)  
It is also depends of model. See Figure 9 of research.
