USC is extremely slow at loading/navigating/installing

[Ignacio Marcoux]

Binary package hint: software-center

Overall performance is extremely bad, even worse considering its a simple app with just a list.

It takes a long time to start. This is really bad and must be solved if it is wanted to be used as a gdebi replacement.

Navigating is insanely slow. Not only that takes a long time to display software lists, but also when scrolling it lags a lot: You scroll, you stop moving the scroll wheel and keeps on scrolling a few seconds.

When you click install, it freezes a few seconds (window turns grey), or it just does nothing for a few seconds, until it is added to the queue.

Hardware: Netbook (any netbook will be the same, since they all use the same processor -n270 or n450-) and some fairly old desktop -pentium 4-
This happends in all machines I know. In most powerful machines (I have a q6600) it is barely noticeable because it can handle it (the same way it can handle crysis) although still eats CPU and is a bit slow.

Some people say "Update your hardware if its slow". Not only that I'm talking about a 2010 netbook which is one of canonical main targets, but also the fact that ubuntu should be able to run in the widest variety of machines, mainly when it can be simply fixed, this is not about bringing 3d in a 486, but about having a simple list of items working fine on a netbook/pentium 4/sempron.

Thanks for your bugreport.

What type of hardware do you have (cpu, memory)? Its not perfect for me, but certainly not that slow. So I wonder what system you use?

A netbook (netbooks are all the same, atom n270, or n450 which has the same performance but lower power consumption). This is bad since:

1) Netbooks are an important target according to cannonical
2) Even if they weren't, a program so (graphically) simple should be lighting fast.

[Ignacio Marcoux (ignacio-dm10)]

Updated the info, I guess it is confirmed now.

Please don't confirm bugs you've reported yourself.

Installing software is now painful. I really liked the new interface, but I prefer the old software center, since it was much faster.
I am in a desktop computer.
When I click to install, the Software Center gets really slow, and it keeps showing the install button. In addition all animations are slow, and even the install process is really slow, and takes a lot of time.
When I am reading the description, and I press install, it never shows that it finished installing, and when I go back one level, it keeps the install button, untils I reselect it.
Im attaching the output of my lshw.
Something is really wrong with this program.
Thank you for the attention.

Please do not nominate a bug for a release that does not have a fix.

thank you

As this is a duplicate but the other report has status high and many more 'affects me' hits, please set this to high too!

WIth Oneiric, on single core Atoms, 1GB RAM its quite slow, but some times it gets extremely slow stalling for minutes, like some cache is trashed. Removing .cache/software-center doesn't solve this either.
