I have a netbook with small performance (AMD C-70 APU with Radeon(tm) HD Graphics x 2) with 1.7 GiB of memory. Elementary Luna is already quite slow. If I update to Freya, shall I expect lower or higher performance?
In my opinion, Freya will have lower performance. I have not a single fact but I remember the "exposé effect" much smoother in Luna that in Freya, for example.
