A few days ago, I upgraded from Ubuntu 12.04 to 12.10 and the upgrade went smoothly. My system is stable and runs well with the exception of Dash.

Dash takes FOREVER to load icons and when I try to switch filters, say from "System" to "Internet", it seems Dash doesn't really respond.

I'm running Ubuntu 12.10 64-bit on an eMachines system with an AMD Athlon64 3200+ CPU running at 2GHz and with 2.5GB of RAM. I'm running Unity.

Any ideas on how I can find out why Dash is running so poorly? According to "top", Xorg consistently takes 30%+ of CPU and the other applications I have running are Google Chrome (5 tabs open, one of which is streaming from Pandora via Flash), Mozilla Thunderbird, Empathy (one chat session open), and rdesktop (connected to a Windows XP system).

Thanks!

Peace...
