>              Labels: performance
>
> Currently path queries do a lot of label collection copying. This has a significant impact on performance.
> As the labels are known and set on the traverser when {{Traverser.split(r, step)}} is called there is no need to call {{Traverser.addLabels}} again in {{AbstractStep}}
> Also seeing as {{AbstractStep.getLabels()}} returns an {{UnmodifyableSet}} the step's labels can be used directly in the traverser. There is no need to make a copy of it.
