I confirm the above-mentioned problems with the Dash in 12.10. I turned off the blur and disabled the Amazon ads, which seems to improve performance a bit. Until at some point the Dash causes the CPU to rise. Population of the Dash takes >20 seconds, type lag of 2 seconds, occasionally the key that I happened to press at that moment causes repeated entries (e.g. "kileeeeeeeeeeeeeeeeeeee...").
