Thank you Mauricio,

I have something to ask you more :)

I know that Yum used only Python, Smart also use Python but the speed of 
smart is very different from yum, what makes the differences? Beside 
that, smart sometime is faster than apt (follow the theory: apt must 
faster than smart because apt is C, smart mixed python and a little of C).
The theory I know is:

Do you know what is the main reason make smart is fast like that? :)
