Why not add a glibc and kernel which are optimized for pentium 4 in FC3 ? This would increase the perfomance on newer PC but also works on older ones by still including the i686 and i586 versions.


Starting with FC3, .i386.rpm and .i686.rpm packages will be compiled
with -march{3,6}86 -mtune=pentium4, so although they will run on
i386 (resp. i686), they will be optimized for P4 (Athlons and newer AMD
chips run P4 optimized code without noticeable performance hit).

Out of curiosity, how do those optimisations affect Pentium M processors?
