It's the same on OS X, imho. I've carried around my preferences and such for some years now, from an old PPC G4 Mac Mini, so I cleared out some Safari cache databases and that helped startup delays a bit, but Chrome's dev preview for OS X still eats every other browser's lunch. Chrome on Linux and Windows are just as fast in my experience but I haven't used it on Linux as much as the others.
