Example for dynamic load imbalances

I'm interested in the load balance behavior of CP2K. I've done some 
measurements already, but I mostly found inputs that lead to small and 
mostly static load imbalance. I am aware of the built-in load balancer, and 
I turned it off for my measurements. Can somebody point me to imput files 
that exhibit bigger imbalance, and maybe even changing imbalance over time? 
I'm using CP2K mostly as a benchmark, so unfortunately my knowledge of the 
actual physics is very limited.
