Applications Center starting too long

[Nicholas Shatokhin]

Ubuntu 12.04 beta 1. Applications Center starting quickly than in Ubuntu 11.10, but it's still too slow.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Hi Nicholas, and thank you for your report. It would be useful to get an idea of the startup time values you are seeing for Software Center on your machine. Could you please open a terminal and start Software Center with the following switch as shown?:

  $ software-center --measure-startup-time

In the terminal output, please cut and paste the following two values into this report (the values shown are for my machine):

** main window visible after: 1.25009989738 seconds
** main window fully ready after: 3.56165599823 seconds

We have sped up startup time quite a bit during the Precise cycle, but there's always room for improvement and we plan to do more work in the area in the next few weeks. It will be helpful to have objective data for different machines as we do this.

Thanks for your help, it is much appreciated!
Gary

[Expired for software-center (Ubuntu) because there has been no activity for 60 days.]

I run it on PC with 8GB DDR3 memory. When I used 4GB and on my laptop with 2GB its too long.

I'm trying to figure out how I can narrow the cause down further but I'm not a python coder so Matthew any hints on where this looks to be coming from would be great.
