The CSS transforms are hardware accelerated by Chrome, but I can imagine this animation is still a bit too much for an EeePC GPU. Maybe with a static map it runs more smoothly, since GMaps is also a bit heavy. However, running smoothly was not the intention of this experiment ;)
Same on a desktop ubuntu 11.04 in chrome.
Also you should really change your root experiments.bonnevoy.com domain to something more interesting than the default centos apache page.
There you go, I made a root with some links to other experiments (guess that's what you were aiming for). Disclaimer: code will be messy!
