3813	Execution time of simCode: created modelInfo and variables scales badly	Francesco Casella	Lennart Ochel	"Based on results from the ScalableTestSuite and from my own large network models, the phase of SimCode which creates modelInfo and variables scales as O(N^1.48^), N being the number of equations.

{{{DistributionSystemModelica_N_56_M_56}}}, at 65000 equations, takes about 10 seconds. A system with a million equations would take over 10 minutes.

There is most likely some operation in this part of the code that scales as N^2^ - removing it would give dramatic improvements on the largest models. I see no reason why this part of the code should take more than O(N) seconds to execute."	defect	closed	critical		Backend		fixed		Per Östlund Adrian Pop
