Hm, okay. That's what I'd understood, but writing the object I'd just
loaded in takes a second and a half on my x86 box, while an image create
takes about a minute, most of which is spent with "Caching catalog ..." as
the status. Perhaps encoding the catalog as a JSON object is the slowdown,
or perhaps I'm timing the wrong thing, but somewhere the two don't compare
properly, which is confusing.
Yes, encoding the catalog as a JSON object (which is part of what
Caching catalogs... does):

Here's one for image-create too:
