I take 2 or 3 second pulls, depending on if I'm going to inhale or not. Easy 8 seconds to pull a cloud and not inhale it. It all depends on the gear you have. I remember almost sucking your eyeballs in, right up to the cutoff with the CE4 clearos to get a good vape. The clearo's vape was a fraction of what can be done now with the right build and power combo. I under power my builds, rarely go over 40 watts cause I have tried vaping ultra low coils using high power and always ended in a coughing fit from the heat, don't know how some can do it.
