Why are the execution times for facility assessment so long?

We have created a TRIRIGA facility assessment analysis for 5 buildings containing a total of 200 building system items. The number of years in the analysis is 100.

We are observing very long execution times and are wondering what is a typical execution time for such a sample, in order to ascertain if the execution times are adequate in our production environment. Can anyone share their experience or comment on the execution times of facility assessment analysis? Or component renewals generation? Thanks in advance for sharing.
