[Bug 876210] Re: Ubuntu Software Center takes a long time to load

[Gary Lasker]

Hi Chrles. The Software Center devs have just returned from the Ubuntu
Developer Summit in Orlando and we have identified the work that we plan
to do this cycle. Performance (and in particular, startup performance),
is at the top of the priority list for improvement in Precise (and for
SRU into Oneiric). We have also identified other areas that need speed
improvement, and will address those as well.

Please note that we maintain a reference startup chart that we are using
to monitor our progress in this area. These measurements are made using
our chosen reference hardware Dell Mini 10, which is a fairly low-
powered machine.

For the previous version of Software Center in Natty, you can see that
we were at about ~3s for startup:

And for Oneiric (and currently Precise), we are currently at ~7s with
the 5.0.2 release (SRU) there:

  http://people.canonical.com/%7Emvo/software-center/mini10-startup
/start-times-oneiric.png

If you take a look at the second graph, you can see that at revision
2516 in software-center trunk we were at about 34s startup (!). This was
the version that was released with Oneiric final. Note the improvement
immediately after at revision 2517 that brings it to about 10s, and then
improves to about 6-7 seconds from there. The software-center version
5.02 SRU in Oneiric includes this improvement.

And of course, we will continue to improve from here. Please keep an eye
on this bug report as well as the startup time charts to monitor our
improvements, and please add comments at any time to let us know if the
improvements are noticeable and if they are making your experience using
Software Center less frustrating and more enjoyable. That's our goal!

Thank you, your help is very much appreciated!

Best regards,
Gary

Title:
  Ubuntu Software Center takes a long time to load

Status in “software-center” package in Ubuntu:
  Triaged
Status in “software-center” source package in Oneiric:
  In Progress

Bug description:
  For a full description of the misery this bug is causing WORLDWIDE,
  see:    Ubuntu    “software-center” package    Questions    Question
  #174730

  This is basically identical to Bug #641899, and I could have just
  attached my name to that one, but somebody decided that bug was too
  broad and so made it invalid.

  Fine, I'll be specific. The UBUNTU SOFTWARE CENTER TAKES TOO DANG LONG
  TO LOAD on Zotac ZBOX with Intel Atom cpu 1.8 GHz and 2 GB RAM. By TOO
  LONG I mean more than 20 seconds.

  I would file another two dozen bug reports on miserable program but
  this trackball I am being forced to use (yes, there's a goon with a
  gun to my head) is driving me nuts.
