This is not update-manager specific. Attached is a tiny pygtk app that demos
the problem.
It takes 1.4s to run on my ati card on maverick and up to 3s on my nvidia card
(with nouveau).

The high cpu-load affect both ATI and NVidia but not Intel graphics as far I've
seen . Myself I have a Radeon 9800 Pro running the open driver that is heavily
affected by this high load.
The libcairo2 1.9 branch might affect nvidia further but the 1.8 branch
causes the same problem i Luci

Just happened to find this bug report.
Have you thought that there is one package behind all this sluggishness (caused
by high CPU load).
The name of the package IMO is libcairo2, and precisely the 1.9 branch (newest
in maverick is 1.9.12.-1 right now, newest snapshot is 1.9.14).
The problem see
mvo, update-manager is working much better for me than before, but like
others I am still getting 100% cpu load from xorg on building data
structures and it is still slower than lucid. If you want to investigate
this more we can schedule a time to meet on IRC again, otherwise good
work so far!

I can confirm this when changing to Ambiance as theme, update-manager
also crashes for me.
High Xorg load and also high CPU load noticed.

The root of the bug, high xorg load, has not be solved so marking it as
Confirmed.
Note that this bug applies to all apps using the progress bar where some
of them generates a very high load for a number of themes.
Tested themes causing high progress bar load
- Ambiance
- Dust
- Dust Sand
- Hanso
I still see this problem with Maverick, even with update-manager
1:0.142.3. Everything is up-to-date, and I am using the real nvidia
driver, not nouveau. I confirm Bowmore's observation that it is theme
dependent; Clearlooks is fine, Ambiance, Radiance and Dust are not.

Further investigations show that it's theme dependent
Test case:
- Panel app "ontv" with some 10-15 channels gives
Lucid cpu load:
- Ambiance 60-65%
- Clearlooks 1-2%
Maverick cpu load:
Ambiance 90% (progress bar longer than i Lucid)
Clearlooks 1-2%

I'm not sure this is the proper way to solve the cpu load for the
progress bar.
The proress bar is used i other apps too and this solutions above then
will have to be specified in a design rule or finally fixed in other
ways. For example, the panel app "ontv" uses the progress bar per tv
channel a

update-manager (1:0.142.3) maverick; urgency=low
* merged lp:~and471/update-manager/fix-bug-386196, many thanks
* DistUpgrade/DistUpgradeView*.py:
- port progress to new python-apt 0.8 API
* merged lp:~mdz/upda
With the help of bbordwell on irc we managed to fix part of the problem
by limiting the amount of "set_fraction" calls to the progressbar.

I am getting this bug with nouveau driver. It takes update-manager over
10 min. to start and xorg is using 100% cpu the whole time. I will try
and look into how to get more info for this bug but I am not very
familiar with xorg or update-manager.

Statu
After upgrading to maverick I have noticed this problem. While update-manager
is in the "Building Data Structures" state, Xorg CPU usage is 80%+ on my
Core2Quad6600. There are other situations in which Xorg consumes an unusually
high amount of CPU time. Examples:
- Frequently adding lines of tex
