I've been dual-booting with Ubuntu and Windows since Ubuntu 9.04. This was the first time I used Ubuntu and was really happy with it. The boot and shutdown time was very nice and much shorter than on Windows Vista. I was pretty satisfied with the general performance of Ubuntu back then. As the versions passed, I noticed, that with every new release the performance is getting worse. I believe one reason could be Unity, since it is still under development. I'm also not really happy with this new UI direction everyone (Win8, Unity, Gnome 3) is heading now. These big buttons and text fields as my screen would be a touchscreen. I would prefer the old (but fast) GNOME 2.x. However this is a complete other topic. I read somewhere that the slow boot and shutdown could be about the network manager.
The second thing is the graphic performance. Unity and the general desktop environment is pretty slow, not that it's unusable, but when I press or click somewhere I notice a little delay. Games, compared to Windows 7, Minecraft runs much smoother than on Ubuntu. And a few other games too.
I would like to know if there are any tweaks or something that I can improve the boot and shutdown time, graphics performance, etc.
