Are you aware of the profile tools inside Pharo ? They capture execution and offer detailed analysis of how much time is spent on each task. One of it can be found in World Menu -> Tools -> Time Profiler

Generally speaking a while loop that runs all the time without any kind of delays is a very popular way to consume 100%. Even if the while loop does nothing it will still consume %100 because even executing an empty loops has costs. Two solution is inserting a delay in the loop so the loop have to wait for 1 millisecond or less depending your demands or just make sure the loop has a very specific condition so it executes only when you need to.��
