Hm, that is strange. It does not even tax my CPU enough to kick it out of its lowest speed state, let alone tax any of the cores.

You must be a better programmer than me.

Hmmm.... My 2.5Ghz Core2 Quad is sitting at 15-20%. Compared to watching the vid on youtube at 5-10% utilization.

I'm running an i5 processor, and when the video was playing my cores jumped from the 5-10% range (background stuff I've got running) to the 25-40% range.

Interestingly, just switching from the demo tab to this HN tab (FF 21 on Ubuntu) drops the cores to the 10% range. They jump again when I switch back.

LOL, my old core2 duo has both cpus running over 80% on Ubuntu with a GeForce GTX260. But when I click on another tab, with the video still playing on a non-visible tab in Chrome, the cpus drop to around 20%. When I click on the video tab again, the cpu ramps up to the 80% mark again. Neat trick.
