Sorry my last post was a bit vague as to the triggers for the
bottlenecks.
To follow up my last entry:
the get_mset() calls are actually made in _get_estimate_nr_apps_and_nr_pkgs
which is called from _blocking_perform_search()
These are Triggered by _build_homepage_view in
ok, so it seems another big bottleneck in startup is Xapian calls.
Specifically calls to get_mset() these calls take over 4 seconds in
total on my machine.
Most of these calls are made from _blocking_perform_search() in
softwarecenter/db/enquire.py
Again aside from upstream optimizations to
I just couldn't leave this one alone. The cataloged_times is just a dictionary
so there is no real need to use pickle to serialise it. I loaded the file into
python and created a serialise file using msgpack instead.
This reduced the file size from 3.1MB to 1.7MB. I then changed software center
I've filled my suggested improvement in the debian bug system for apt-
xapian-index I guess its now up to upstream to agree.

Ok, turns out the xml parsing isn't to bad after all. I tracked this one
all the way back to:

if os.path.exists(CF):
try:
cataloged_times = pickle.load(open(CF))

I still have to verify this with actual benchmarking but one place that
looks like it will benefit from optimising is here:

Yes, Ubuntu Software center is horribly slow, inconsistent, hangs,
poorly designed and confusing. The add-on section is weird too. If you
click Aply changes in the addon section it just goes ahead and starts
installing the software without confirmation. Who designed/wrote this
stuff and how did
Take a Geany for example - clicking on any additional package freezes
Ubuntu Software Center for 30~60 seconds... additionally at that time
compiz and Xorg consumes suspiciously lot of processor time.
