Roy was also surprised when I told him this the first time, but it's really true. Well, at least, for 8 CPUs, the per-CPU memory usage drops a lot when using ghosted vectors. That's why I pushed their implementation. From 8 to 24 CPUs (that's running right now), however, the per-CPU memory usage does actually not decrease essentially any more.
