prefered kernel configuration?

[Joris Huizer <jorishuizer@planet.nl>]

Hello,

I have a simple question: I'm using an AMD Sempron machine, and I build 
my own kernels; I'm currently using the 386 configuration in the linux 
kernel, as I didn't know what option would be best to choose...
What is actually the best option for best performance? I was wondering 
whether 686 had pentium-specific optimizations which is why I didn't 
choose that one
I'd also be very thankful if somebody could give some links to sites 
discussion what options to use best in general (for other similar 
configuration questions)

Thanks :-)

Joris
