The thing is that very few people are facing this performance issue because again : the feature just doesn't exist at all in Vanilla Construct : this is the main issue.
I was talking about "On signal", a feature that does exist. It might not do everything you want, but it does exist, and I thought its performance should be OK, even if not perfectly optimal. That's what I was talking about, but I think you're trying to talk about a whole bunch of other things, which I think makes it hard for me to get anywhere in this discussion, so I think it's best I stop posting in this thread.
