Good to hear!
One nice way is to use volume rendering in Paraview. Please note that this is not in any way OpenLB specific, we just export VTK that can then be post processed in e.g. Paraview the same way as an OpenFOAM case.
On the performance question: In that case you simulated without any parallelization (or even vectorization for the single process). For your hardware OpenMP will likely perform best but you can also use MPI. There is documentatiom on this on the user guide and also in the comments of the config.mk file where you can adjust the parallelization modes.
