This question was marked as an exact duplicate of an existing question.

12.04 has a few performance updates i think, because lots of apps opens quickly if compared to 10.04 you can upgrade to it if you want.

Before updating my computer, my computer opens lots of the program quickly. But, I think if I upgrade to 12.04 and making regular update, The result will be same. – user1362516 Apr 29 '12 at 10:42
