	Recompiling the kernel may improve the performance of some CPU
bound operations if you adjust optimisation flags and compile to a specific
CPU architecture. However unless your system load is such that it is CPU
bound in kernel space it is unlikely to make a difference to the overall
performance of the system at the cost of increasing the risk of hitting
optimisation bugs.

	Very high performance routing is one of the few applications I can
think of where I might expect a noticeable difference from optimising
kernel code.
