little lags animating large objects

Question

I recently discovered velocity.js, which is really great. I am animating a pretty big SVG graphic, which slides through the screen (about 5k px width). It looks somehow like this:

$($(element)[index]).velocity({
    translateX: [-distanceMove], 
    translateZ : 0
}, {
    duration: 60000, 
    easing: "linear"
});

However, I experience little (really minor) lags in all browsers. Does anyone know how to get rid of these? I am guessing it could be the size of the SVG. Should I cut it into pieces? Would that make a difference?

cheers,
