I've discovered recently that its the video hardware and how that interacts with the precise (sic) choice of graphics driver that governs Unity speed.
cletus: you can test my hypothesis by logging in with the Unity 2d session and seeing if the UI becomes more responsive. Scaling (super-s) will be 'ragged' without 3d effects but should be faster.
drivebyacct2: what is your graphics card and what driver? I need a new desktop box soon myself...
I'm giving Unity a try and I have to admit its a little fussy and busy. My fallback is Debian with a tiling window manager (dwm) so I've been going in the 'menuless' direction for some time.
lvillani, yes, the nvidia form of this bug and its associated work around has improved the performance of Unity with my old desktop significantly. Lots of searching Ubuntuforums and the interweb had not turned this up, so thanks.
Oh, sorry. I don't count Unity/Compiz. I thought you meant the general performance of Ubuntu is bad. I would highly, highly recommend you give Gnome-shell a shot. I have some el-cheap-o Nvidia card with the latest from the Ubuntu repos (they have a new repo that Jockey sees that will let you use the latest from Nvidia rather than the standard distro one)
