processor choice in kernel config

I am making some production kernels tuned for individual hardware platforms. I do not want a ton of kernels unless it makes sense to do so. Specifically, for a non-graphical,non-sound dedicated network application server, is there a any justification (performance/reliability) for me to make a PII, PIII and PIV kernel (all other things the same for argument sake)? I would rather just have a PII kernel to run on all if there is no difference...

Obviously there are performance issues and others as well, else they wouldn't have bothered to make provision for the different CPU's now would they?
However, I believe that most of the "advantages" of compiling the kernel for a specific processor has to do with the added instruction sets for the processors, which is mainly aimed at graphics and multimedia performance enhancements,so in your case there might not be a difference...
But, to be on the safe side, compile them, and do a test to see if the advantages are significant or not... Only REAL way to tell methinks

Testing performance is not a problem, but reliability is; hence the ee question. Yes I also feel I would gain nothing in my non-multimedia usage. Just looking if someone had the real low down on intel & linux. I would assume a that non-pentium (i386) would be much slower, but the pII and PIII difference??
