How can I improve performance and user experience in 11.10 (boot + shutdown time, graphics, ...)

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.

Did you install additional drivers for your graphics card? Try to install one using jocky-gtk.

Install preload which loads recently loaded(but not running now) programs data in the background so your system can load that program faster when you want to start it again.

Go to ccsm > Unity plugin>experimental . Change dash bar to static or no blur. Which reduces the delay of unity dash.

Must use swap, at least 1GB. If you did not keep a partition for swap then don't worry, you can create swap file without delete or create a new partition. Check here Just copy paste the commands in terminal.

Remove unnecessary programs from you startup list.

sudo sed --in-place 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop

Run the command first which will display all of your applications in "start up application"

Install laptop-mode-tools which will increase your laptop's battery life.

Add the line in /etc/sysctl.conf

sudo gedit /etc/sysctl.conf

vm.swappiness=10 [add the line at the end of the file]

This means your system will keep the cache in ram instead of swap as much as possible and your system's performance will increase.
