I just installed Ubuntu 14.04 in a VirtualBox machine, which I am planning to use for Java/Web development. After my first steps, I noticed that the CPU usage is very high even when I do simple tasks like browsing files with nautilus. In htop I can see that it is compiz utilizing the CPU heavily.

I have already tried to disable the effects and animations with compizconfig-settings-manager, but it did not change much. I would like to keep the new Unity interface if possible.

A list of steps that leads to the best result would be great.

If you don't need compositing/desktop effects, then Xubuntu would be the better option.

It has a nice tool in its Settings menu to turn them off, and quite frankly you won't lose anything by installing Xubuntu if you're only going to use it for web/java development. You'll be using the same apps as you would do in Ubuntu.

Have a look at this answer related to 12.10. For me it works great now.

The cpu load goes up, because it does a bad job at performing GPU tasks... but the CPU is forced to do so... just have a look at the linked thread.

You could just run a completely headless ubuntu box and do everything via command line.

Otherwise lubuntu and xubuntu are pretty light weight, you could try openbox.

Command line is the best way, however.
