Installing packages manually is slow

[Jussi Lind]

Installing debian packages manually via Software Center is too slow.

Steps to reproduce:
1) Double-click a .deb package in Nautilus
2) Wait for USC to open
3) Click install when the package details is shown

What should happen:
The actual install process (starting when user clicks the install button) should be about
as fast as installing the package in the terminal with sudo dpkg -i [package].

What happens instead:
On my machine USC is 4-5 times slower than plain dpkg. I used my own game as a test application:
dpkg -i: 4 secs
USC: 20 secs (time elapsed since the install button was clicked and password given)

I repeated this several times with similar results.

The test application (dustrac):
