Slow / unresponsive unity while launching applications

Some of this is fixed with last weeks commits, but there is still memory leaks which seem to be tied to the bad performance over time

With the today last update Unity has become more quick and stable. Good work guys!

This bug was fixed in the package unity - 0.2.40-0ubuntu1

Coming together nicely, isn't it! Great work from team Unity.

Still very unresponsive on Eee 901.
Especially the application browser that takes several seconds to display applications.

I'ts kind of ironic that the regular gnome desktop performs better than the unity based netbook environment that was targeted for this kind of hardware.

I also would say that the "applications" launcher is too slow on an Asus EEE 1000HE... The previous netbook launcher was much faster when you had to start an app that is not in the favorites...

I would call Unity "unusable" on a Lenovo S12 ION (nvidia powered).
-- Several seconds to react on a click on sidebar element
-- Filebrowser shows no icons, or needs >10sec to show icons, and icons are humanity icons and not the ones from selected icontheme
-- long lags when: scrolling, open programs, ... much more
-- ...

I just wondered because the Desktop Edition runs fast and I can run compiz with GPU eating effects without any performance issues, but Unity coded to run fast on Netbooks makes it unusable on (normally more underpowered than desktops) Netbooks even WITH hardware accelerated graphics . I sadly had to reinstall 10.04 UNR for best experience and will try in 11.04 again because of mentioned performance lacks. Maybe I will install Unity on a testing partition on my NB to track performance updates and see how it improves.

Specs:
- 1.6 Ghz Intel Atom
- 2 GB Ram
- nvidia ION

I have the same problem, what is the solution?

Thanks! but there aren't any recommendation in this post, only more people
with the same problem. ¿have you the solution?

"Hi everyone - I'm one of the devs that have spent extensive time chasing this slowness issue. I assure you I can relate to your disappointment over a sluggish system. It's buggering me a lot as well.

The problem is that on some systems Unity runs perfectly fast (for instance on my Eee 1001, intel 945GME, Atom N270, which is definitely *not* a high end netbook by today's standards - on the contrary :-)), while on other systems (also with much higher specs) it runs very slowly. This makes it pretty tricky to debug if you don't have the right hardware as you can imagine.

So; any thoughts, tinkering, playing around, or hardcore profiling you guys do are most appreciated! While I can see that there is a lot of general slowness - it would be most valuable to hear if *anything* runs fast? That could make it easier to narrow down the problem.

While you're at it, you might also want to try an run Unity with the environment variable CLUTTER_VBLANK=none set. This has reportedly fixed the issue for some. To test it out simply run 'CLUTTER_VBLANK=none mutter --replace' from a terminal. If it works for you, you can make it permanent by executing 'sudo echo "CLUTTER_VBLANK=none" >> /etc/X11/Xsession.d/10unity-quirks'.

Thanks for all the input so far!"

Hi again! Thanks for the quick answer, I didn't see this posibility the
