Comment #2 on issue 15310 by robkroeger: Panning in Google Maps is slower  
in Chrome than in Safari and Firefox on Mac OS X
http://code.google.com/p/chromium/issues/detail?id=15310

I would claim that Mac OS Chrome is generally slow to do screen updates  
compared to Safari. So, while V8
performance is competitive with squirrel fish extreme, the display  
subsystem seems to require sizably more CPU to
achieve the same result as does Safari.

As a simple specific example that makes this very clear, consider  
http://nerget.com/fluidSim/  The JavaScript code
running in a render process uses ~90% of a single core and delivers  
performance equal or better to Safari4.
However, the browser parent process also uses 85% of the cpu (MacBook pro)  
to update the display while Safari
merely raises the Window server CPU load from ~3% to 7% to achieve the same  
result.

Perhaps a way could be found to alter the renderer to (safely) write  
directly into the framebuffer? This would
probably be good both for the <video> tag and would seem desirable to make  
O3D on chrome a viable gaming
platform.
