On 11.10 Oneiric, software-center takes way too long to load.
Note that it was less bad on 11.04 Natty.

The startup time has not increased appreciably since my most recent
comment, even with the many additional new features that have been added
to Software Center since that time. As always, startup time results for
the Dell Mini 10 reference machine can be viewed here:

It seems like we may at this point be under the 5 second target for
benchmark hardware (software-center trunk at revision 1416 on mvo's Dell
Mini 10). Once we get some reasonable measurements on the Mini under
cold-cache conditions (per comments above) we can make the
determination.
A graph of the
A cold cold cache is going to be a problem on the mini.
$ echo 3 | sudo tee /proc/sys/vm/drop_caches
$ nautilus -q ; setsid gnome-panel --replace; time python -c 'import gtk'

Just importing "gtk" from python may take 4.5s already.

Suggestion for measuring with cold cache:
# first, drop all caches
echo 3 | sudo tee /proc/sys/vm/drop_caches
# restart gnome-panel and nautilus to reload most of GNOME/gvfs/GTK/libc/etc
bits back into cache:
nautilus -q
setsid gnome-panel --replace

Seeing the improvement on the current graph is awesome. However, most
USC launches will be cold rather than warm, so I think we really should
start measuring cold launch time instead. How can we do that in a non-
tedious way?

improvements). Initial graphs are here:
