well, and that is why the options are there
and that's my static build for servers with static libx264
on x86_64 there is no noticeable impact at performance
the same for PHP, APache, Postfix. Dovecot, MySQL.......

at least on i7-3770 and Xeon E5-2640

some of the performance penalties may be negated by the compiler-optimizing
for recent CPU's and agin: that is why the options are there and rpmbuild
exists to make predictable and deployable packages on test-machines
