Bug Description

The delay is always there. There seems to be no delay in Gnome for the comparable situation.
I expect the Dash to appear immediately. As fast as you'd expect that a character appears when you type text.

Maybe it's because the transparency effect in Gnome uses less archaic ways of doing it, but I'm not sure about that. I just noticed that the dash transparency is CPU intensive, but that's another problem.

This could be related to the Nvidia driver, since the dash opens as quickly as the Gnome shell activities overlay does on my Intel-based system. Tested on AMD too, and the results were similar.

Can you describe the length of the delay? As there is a 90ms animation when opening/hiding the dash.

I get this on my Ubuntu 13.04 system (GPU: NVS 3100M/PCIe/SSE2, driver 3.3.0 NVIDIA 304.88), delay is about 2.5 seconds between pressing Super and the Dash appearing.

I do not get this on my (lesser-powered) Ubuntu 13.10 system with Mesa Gl drivers: the Dash opening is almost immediate.

I have a 1.5 second delay when opening or closing with the Super key. All actions that include Super, such as Super + W (show all windows) have the same delay. Opening with four-finger tap on the touchpad or by clicking the dash icon on the launcher is much faster - instant.

Could it be a timeout set for detecting Super? Intel Graphics.

My old AMD APU had a much longer delay, like 2-3 seconds.
