I hate to be that guy but this takes up 45% cpu under firefox for a simple spin animation.

  Same here, on Chromium 12 (wait, 12!?! Time to go fix that...) on Ubuntu 11.

  CPU time measurements, especially percentages, get very fuzzy when the CPU isn't loaded. I'm on Chromium 12 on a Fedora 15 box. Top reports ~25% (on a dual core Arrandale, so that's about 1/8th the available CPU time), but checking the clocks more carefully shows that they're spending half their time in sleep states and never moving from the 1.2GHz base speed (this model turbos at 2.9GHz). So my envelope tells me this is about 4-5% usage vs. a fully loaded system.

I see the same problem in Opera too, except it's even worse (the animation lags, and it hogs a whole CPU core). Explorer is better than Firefox and Opera, but still pretty high CPU usage. The only browser of the ones I tested that it seems to be relatively fine in is Chrome.

Less than 10% CPU for me, with Firefox 6.0.

My gut feeling is that if you rendered the different stages of the animation into multiple images using canvas and just toggled their visibility, you could get better performance.

Didn't realize this. Oh well. It's still cool and interesting, but I guess never that feasible.

On Opera, whenever the spinners are visible, page scrolling is extremely laggy and slow.

Interesting replies. 0% on IE 9 and Chrome 13, and 15% on firefox 5 (which translates to 60% of a core). Running Win 7 x64. Aaaaaand... just upgraded to Firefox 6. 0%. Rather fickle piece of javascript, eh? And just because why not: IE 8 in a winXP vm: 0% IE 6 in a winXP vm: 0% Doesn't work in FF3.
