At first, just as badly as before.  System::project_vector() is still
one of the things we use a serial vector for, and while that's on the
list of ParallelMesh items to be fixed, it's not high enough on the
list.

You're not the only one seeing that.  We'll definitely fix the poor
scaling there before we consider ParallelMesh "done", but there will
probably be a 0.6.9 release first once ParallelMesh is in a "correct
but not yet complete" state.
