Thanks Nils you for sharing your experience. I may have to look into MeshWorker, but currently I am using WorkStream. I think with FEInterfaceValues, we can still compute the gradients and then compute the jumps, which seems easier to implement, than switching to MeshWorker. I will give that a try first.
