well i cant say for sure anything about the mesh stuff cause i haven't tested it, or haven't tried it, but i know that when i wrap a 20x20 mesh onto a sphere, it runs pretty damn fast even in a cap with other models, but i dont think having the 400? quads (im kind of tired and im not sure if my are of the mesh equates to number of quads) would be faster would it? it seems it would take up way more memory, and be a lot bulkier to handle, but like i said, ive only tried the mesh way of doing things, and im basing it on the good performance i got with it, not to mention i dont know how youre handling face wrapping, and that could very well be a contributing factor.
anyways, i think anyones that dabbled with making models knows just how unsuited construct is to it.
a mesh object would make it so much easier and better performing anyways
