Stree test questions

I watched the stress test video for shapr3d on ytube and it was amazing. However, when i did this pattern thing,it was terrible. For example,I make a shape and Copy it by rotating 12 times. Then my ipad stuck and nasty ‘slow mode’ started. This happened all the time even if i union all the shapes. I thought that might help because the total shape number was reduced. Did you run the copy and rotating test? Thank you.
