Note-Pencil-20 Large Model Tips:

Make Auto-rebuild Inactive. Then experiment. Many commands continue when Rebuild is inactive. Then make it active and then inactive again, every 4-5 commands to rebuild.
Number-of-Steps : Make 90, or even less. You do not need many steps for a machine cycle while you build the model.
Show Model in the Mechanism-Editor : Do not use as you edit model's kinematics, if possible.
Image Quality : Change to 'Low', then save and re-open the model. Do this when there are many Solids in the model.
Spin-Box tool. In each dialog-box, do not use the Spin-Box tool when the model is large, because the model will update after each click. Use your keyboard to enter new values in each data box.

Note-Pencil-20   Toggle Auto-Rebuild on and off at least one time to the always up-to-date state before you do important analysis with your model.
