I resolve it,
The problem was not in Fedora or PHP and times have decreased from 10
seconds to 0.2 :)
The problem was in the file /etc/hosts, when i started develop i added a
line to resolve the domain while updated the DNS, later i don't remove it,
this probabaly cause a redirection that increase response times
considerably.
Thanks for all
