How to improve the simulation time of MATLAB Simulink model?

Currently I am simulating Kundur Two area system with induction motor as a load. When I simulate the model with induction motor load to observe the damping ratio and frequency of oscillation by linearizing the model using the linearization APPs of the Simulink at operating point of 10 sec, the simulation takes more than 24 hrs (very slow) to complete the linearization. Does there any ways to improve the simulation speed with induction motor load.

Looking forward your comments and answer!
