Well im not sure but I once read in this forum that periodic events and wait for condition shouldn't be used only if there is no other way to do it.
Ask yourself this what makes the "condition" be true?
And if the answer is a trigger or a event you can use, you should change it.
I can't tell you much about network traffic, but you can make it as i say above independently on if it works with the "wait for condition" will be better.
Sorry if that doesnt answer your question.
