Description
Please check the latest -d=newInst --daeMode report and look for the DistributionSystemDC.ScaledExperiments.DistributionSystemModelica_N_XX_M_XX models.
The newly introduced selectInitializationVariablesDAE function takes the following times to execute
| N | M | Time |
| 20 | 20 | 2.24 |
| 28 | 28 | 8.95 |
| 40 | 40 | 50.87 |
Please make sure the function scales properly with the system size.

This is only a performance issue when the NF is used (and then daeMode is not needed).
