Unity and its apps open too slowly whenever I open one. It takes a while for them to appear completely. Everything works properly when the window is already open. The biggest problem is with the dash: it's SO SLOW when I'm looking for an app although I have removed some lenses.

What should I do or what can I do? These issues only occur with Ubuntu 13.04 and 13.10 whereas 12.04 works AMAZNGLY but I have issues when updating a package or installing a new one, that's why I don't opt for that one.

Specifications: RAM: 2GB, Processor: Intel® Atom™ CPU N2600 @ 1.60GHz × 4, Graphics card: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits)

Which package do you have problems to update or to install? –  MadMike Oct 20 '13 at 11:08

Seeing this: > Graphics card: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits), I think it could be some gpu driver issue, please find out the gpu model, and google about installing the correct driver for the model on 13.10 and later. –  xgdgsc Apr 22 at 6:17
    
I have the same problem with Dash and no tweaks helped rendering it faster. One thing which does help is using Super + A instead of just Super to open applications. I like Unity but due to this slowness I moved to Gnome 3 for the time being and am loving it. –  To Do yesterday

Had this problem too. Re-installed 13.10, same result. Then I remembered to install Ubuntu Restricted Extras which solved the very slow desktop.Run the below command on terminal to install ubuntu-restricted-extras,

sudo apt-get install ubuntu-restricted-extras

It could also be the performance of your computer. Some computers can't handle 13.04-13.10 as well as they did 12.04. (I've also seen the reverse happen in many cases)

At any rate, there is a tool in the default repositories called Unity Tweak Tool that adjusts the visual effects of Unity however you want. A lot of these adjustments increase performance, and make it so that it doesn't run super-slow.

You can find Unity Tweak Tool in the Software Center, or you can directly install it with Terminal by pressing CTRL+ALT+T, and typing sudo apt-get install unity-tweak-tool
