You don't need metaclouds for this, simply load an atmosphere with clouds in it. Then take your camera and fly through it. The slow rendering is normal, I'm afraid, there is a lot to compute when the camera is inside a cloud layer (cloud density, internal shading, shadow casting inside the volume, light intensity based on cloud density, and the rest of the scene has to be rendered also based upon cloud density at each sample point).
