Just some heads up:
http://www.chromium.org/
http://dev.chromium.org/
The thing of importance:
http://dev.chromium.org/developers/h...ructions-linux
http://dev.chromium.org/developers/h...tructions-os-x
As for the speed, you might also see similar speeds on other Webkit browsers, i.e:
www/midori.
Looks like it's already possible to run on Linux and OS X, might even be possible to build on FreeBSD...
