I have been doing tests under Windows 8, and there is no question that SeekingAlpha's pages are taking some very large amount of CPU, continuously. If you have more than one SA page open in more than one Chrome browser tab, the effect becomes even worse. On a computer with 16 processor cores, I was taking up nearly 50% of the CPU on all 16 cores!! When I close down all SA tabs, CPU use lowers to 13% on all 16 cores.
