Bug Description
Using Unity-2d, the dash (or unity-2d-places, or whatever its properly called) takes almost two seconds to open. This is far too long when trying to quickly access applications.
I've reproduced this on one system I connect to via xdmcp, as well as natively on a different system. The second system runs unity-3d just fine, and clicking the dash there opens in under a second (still there's a noticeable lag, but its much better then unity-2d).

Rigourous profiling needs to be conducted and reported back here.
For now, the quick profiling that I conducted led to the 2 following culprits being identified:
- (blurred) background is making us take a screenshot of the desktop twice for no reason /code.launchpad .net/~fboucault /unity- 2d/windowimagep rovider_ remove_ timestamp_ hack/+merge/ 84662
Fix at: https:/
- everytime the dash is opened the home page is reloaded whereas we could just not destroy the home page /code.launchpad .net/~fboucault /unity- 2d/dash_ no_unload_ page/+merge/ 84672
