Interpreting results

Null-check then call takes most time. It is the most common way to write the code. Null-check without call (func is null so no call) takes the least time. Again, it is the most common way to write the code. Just calling the empty func takes is a middle result.

In situations when we are sure there will be many calls of the listeners, calling empty looks a better strategy. In situatons when we are sure the most listeners is null, null-check first looks a better strategy.
