iOS FPS decline after upgrading from 5.4.3 to 5.6.4p3 - Physics.TriggerEnterExits

My game was running at smooth 60fps on iPhone 5c when exported from Unity 5.4.3. But we upgraded recently to Unity 5.6.4p3 to solve a MonoDevelop crash, and now our fps has dropped to 45 at best.

The profiler shows big spikes resulting from Physics.TriggerEnterExits (each time we move the floor & buildings in the scene which occurs about 2x/second), which was never an issue before. This glitch appears to be what is driving the decline in fps.

Any ideas how to address Physics.TriggerEnterExits spikes? We never had them before the upgrade to 5.6.4p3.

Thanks in advance for any ideas! Pete
