As an example of the performance improvement, on the 'nodes/' page with 10,000 nodes registered, I can load all 10,000 nodes and their mac addresses in 5s with prefetch enabled. Without it, the page takes something like minutes to finish. It was long enough that I just got an OOPS.

On a page with 100 nodes, it was 20ms vs 57ms. With 1000 nodes it was 150ms vs 530ms.

So while we want to do pagination, we still want to avoid doing a lookup per object.
