4470	Bad performance of tearing for large scale models	Patrick Täuber	Patrick Täuber	"The execution time for the postOptModule `tearingSystem` is quite bad for large scale models, e.g. from ScalableTestsuite.

The situation has been improved a lot by [https://github.com/OpenModelica/OMCompiler/commit/767bebdf198ccf7a8d54afab11440d158ac182d6 removing the loop check] from differentiation.

The current times for tearing for the `BreakerNetwork_N_XX` models can be seen here:
[https://trac.openmodelica.org/OpenModelica/ticket/3816#comment:11 #3816]

The performance should be improved further. I will soon add some more times to compare."	defect	new	high	Future	Backend				Francesco Casella Henning Kiel
