So here's my problem: Ubuntu on this notebook/ultra-book is just too slow!
I'm now using UEFI installation because with the standard one there was the power's problem (100% CPU usage on AC-in). I'm waiting 14.04 release to update my machine but my question is why my computer is just so slow in many situations (Firefox open with some other applications, etc). The big problem is that Windows is so fine!
So I'm investigating to find those machines problem. (Just to now i hate Windows and I'm an Ubuntu user since I was 15..). Here's a screen of one of those strange situation.. doing nothing a my CPU is just like that:
So please help not for me, but for the Community. Thank you all!
