Description of problem:
This is not a bug but a wish. Unlike in fc1, if I recompile the kernel
for Pentium 4 its performance slightly increases comparing it to i686
plain versions in fc2. It isn't so in fc1, where the i686 version
appears to be faster than the P4 version. So, I think it would be a
great idea if you build specific RPMs for Pentium 4 and Pentium HT
Version-Release number of selected component (if applicable):
all fedora core 2 kernels
Steps to Reproduce:
1.install the i686 kernel build
2.recompile it changing the processor type to Pentium 4
3.The recompiled version is faster!
Actual Results: P4 builds are faster than i686 builds
Expected Results: to release specific P4 and P4SMT builds or at least
a i686 version that is faster than the P4 version.
Do you have any numbers to show that a P4-specific build is faster?
