OK, so try the other two options.

I tried this code with 5 separate labels and it showed up with the same degree of smoothness as using one label. On my older and slower machine it is not 100% smooth but that is unaffected by the number of labels on the move.

I would think that if your computer is processing other things at the same time, this would impact the level of smoothness. Your code on the other thread was really inefficient - is that being executed while this movement is supposed to happen?
