Unity dash is really slow and unresponsive, it takes between 5 and 20 seconds just to load.
I'm running a laptop with 2gb ram, AMD Turion(tm) 64 X2 Mobile Technology TL-64 × 2, Gallium 0.4 on ATI RS690 graphics. The original install is ubuntu studio, which i have added ubuntu desktop to.
As a test I did a clean install of ubuntu studio, then ran updates and added ubuntu desktop + unity, this had no effect.
The output of /usr/lib/nux/unity_support_test -p is:
OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RS690 OpenGL version string: 2.1 Mesa 9.0 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes
sudo lshw -C video gives the output:

Edit: I used system monitor to check CPU and memory usage, despite unity very slow and unresponsive CPU usage never went above 50% neither did memory use.
I'm pretty sure it's something linked with unity dash as once programs are open they run relatively fast. There is no more lag than I would expect browsing the web or typing this. The problem is when i press super key or ALT and try to type, I could have a nap before it displays what I've typed. Also the side bar is unusable, it takes forever to appear if at all and disappears to quickly for me to click on anything.
sudo hdparm -v /dev/sda gives:

sudo hdparm -Tt /dev/sda gives:
