Hello.

When we play the Factory Flow Simulation, we can sometimes meet the performance issue even though we set the Simulation Options like the below.

At that time, we also need to check Operation mode of In-Zones. 

The default is Push mode. When we run the simulation with Push mode, we can see Products stacked on In-Zones. This means that more calculations for statistics is being processed for more products. 

If we change the Operation mode to Pull for In-Zones, products are created when necessary and this consumes less computer resources. 

The model in the below video is simple, so there is no performance issue. But if you deal with the big model, you can try this In-Zone’s pull mode.

Thank you.
