Recompiling kernel

Hi, I use SUSE 10 Proffessional Boxed Distribution. When i check the kernel configuration the processor type, for which the kernel is built , is 586. Will recompiling the kernel for the processor present in my machine improve the performace of the kernel? If yes then what processor type should I choose for my centrino ( is it Pentium M or Pentium-4 M , I don't see centrino in kernel configurations ). Does choosing the option of Low Latency Desktop Preemption a better choice than Unforced Preemption Server which is default for my centrino Laptop. -- Chaitanya Chalasani ------------------- "The ultimate truths of nature are so subtle that they can be revealed only under immense silence"
