SUPPORT: CPU Guidelines       1: Effective as of January 1, 2007   Here are three examples of advertisements that were "out of spec" and provided poor user experiences. Click here to view examples that are "within spec". There are two types of usage, "running usage" and "spike usage": Running Usage: This is the amount of cpu power utilized after a flash file has completed its primary series of animations and is sitting "idle". Spike Usage: This is the amount of cpu power utilized when fluctuations, "spikes", occur during the primary series of animations. - Occasional spikes are normal as flash files proceed through the timeline but the key is to avoid non-stop spikes because each additional fluctuation " taxes" the users CPU. - Even though this creative has quite a bit of the timeline that is below the red zone, it still spends most of its time in the red zone or escalating towards the maximum we allow. - Creative should not exceed more than 30% of available CPU for more than 50% of the run time. - We define a small "spike" as one with a max duration of (2 - 3 seconds). A small spike of 20%-30% is normal. If your CPU Usage jumps up to 50-100%, the Flash file may need revising until it uses less CPU resources.       - This creative (below) essentially spends most of the timeline, of the ad, in the red zone - constantly demanding cpu power. - Even before arriving in the red zone, it spends the majority of the first portion of the timeline skyrocketing towards the red zone.         - This creative (below) essentially starts off on the wrong foot in launching into the red zone and remaining there for such a long time.
