SUPPORT: CPU Guidelines       1: Effective as of January 1, 2007   Here are two examples of advertisements that were "within spec" and provided positive user experiences. Click here to view examples that are "out of 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. - This is an example of a good ad because even though it has "spikes", both running usage and spike usage are consistently below the red zone. - 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) utilizes very little cpu power, thus allowing the users PC/mac to focus on other aspects, such as loading the page quickly. - This creative also never "spikes" into the red zone.
