This is a test that shows that overall it’s not a good idea to leave a webpage open on your machine with something like a Flash animation running for long periods of time, especially a laptop or netbook. As expected, CPU usage goes up greatly with any kind of Flash on the page, some browsers hitting 80% on a single processor core. As many of the browsers use plug-ins or extensions, this would affect all these scores greatly. For example, a Flash blocking tool would increase memory slightly, but load times and CPU usage would be reduced. Total CPU usage 228 megabytes!
