Chrome taking up CPU on particular urls At least a few times a day I get disturbed by high Chrome CPU usage... I have to open Chrome's Task Manager and see which tab is taking up CPU.

For example https://www.ethereum.org/ always takes 20-30% CPU. 

Today I had the same happen on a TechCrunch url.

Could it be some extension? I just checked https://www.ethereum.org/ in Incognito tab with almost no extensions and it was the same - high CPU load (30%!)

I'm seriously considering swithcing to Safari because of this and some other issues with Chrome recently :/

Any comments / solutions to this?
Safari 7 is documented in many Mavericks reviews to be better at extending battery life and CPU usage. That ethereal link has an animation in the background, I'm assuming that's what's using your CPU.
