I have around 40 Staff Members in my current model which hasn't been an issue until I recently added half of them to my time table. This Upfunction associated with these time tables has a process flow that can be seen in the screenshot below.
With only the Staff portion really being utilized.
After running the model to time 240 where Shift 1 goes on break and Shift 2 goes on I get a massive lag spike and my performance profiler looks like this.
With the Largest Blocks associated with
Tools/Flows/Shift Schedule/ Release Staff/ Active::Start
Any Idea why this release staff is taking so much processing power?
