Counting how many times a function is called

Question

I want to change context (Rdx, Rax etc.) everytime a specific function gets called. My solution: I seted up a breakpoint at function event.get_thread().set_context({"Rdx" : "bla bla"})

My problem: The FPS of the game drops to 16 Is there another method to do this without FPS problem ?
