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.
I'm mystified by image-create taking a minute for you, since on my
system, this is the result I get with gate tip:
$ ptime pkg image-create -p opensolaris.org=http://ipkg.sfbay/dev /tmp/image
real 15.087369854
user 12.176858676
sys 0.356875532
A pkg refresh --full is comparable:
$ ptime pkg -R /tmp/image refresh --full
real 18.121138142
user 12.110212651
sys 0.357763138
And the /tmp isn't the reason for the fast times, using my ~/ instead
for the image gives me only slightly increased execution times (.3s
roughly).
