I'm not quite ready to send out a webrev for Phase 2 of the catalog work
yet (although all of the test suites passed at last check, etc.) and I
really should be in bed now. But, the indescribable satisfaction I have
from the following, preliminary client timings below should justify the
pop culture reference above:
Publisher Setup
===============
$ pkg publisher
PUBLISHER TYPE STATUS URI
opensolaris.org (preferred) origin online
http://ipkg.sfbay/dev/
contrib.opensolaris.org origin online
http://ipkg.sfbay/contrib/
extra origin online
https://pkg.sun.com/opensolaris/extra/
punchin origin online http://.../
Timings
=======
The timings below are higlights from a comparison of a build 117 pkg
client vs. my workspace.
/ is my build 117 system root (that does *not* have redistributable
installed; only about 728 packages are)
/mnt is a beadm clone of my '/' that has been upgraded to the new image
format (at a one-time cost of 45 seconds).
The first timing listed is the old client, the second timing listed is
the new client. And yes, I have performed diffs of the pkg list output
to confirm they are identical.
time old_pkg -R / list -afv >/dev/null
real 0m9.443s
user 0m9.308s
sys 0m0.109s

Summary
=======
As Bart says, "...the only way to go faster in software is to do less."
I still have some more testing (beyond the test suites) of my own that I
want to do, but I'm confident that there is little left to do.
Look for a webrev for Phase 2 of the catalog work very soon.
Cheers,
