Which isn't much in my experience.  Most distro stock kernels are
already arch-specific and optimized fairly well.

GCC isn't known for it's wonderful optimizations either, but rather its
portability.  Now if you could build the kernel with an Intel compiler,
or something, then it might be faster.  

But for most of what people do with Linux (GUIs etc), 90% of the
performance of a system in library optimizations and prelinking.  Total
kernel throughput is all but irrelevant for most folks.  In fact most
distros now are optimized for apparent GUI performance, so the preempt
stuff, low-latency, and O(1) scheduler are enabled, which doesn't
necessarily increase overall performance.  With a lot of these
mechanisms, responsiveness is given priority over performance and
