Subject:   kernel optimization

I haven't yet found notes on optimizing the kernel by
telling the compiler I have a Pentium rather than just
a 386-compatible processor.  I presume these lines
in the kernel configuration file deal with this:

machine         i386
cpu             I386_CPU
cpu             I486_CPU
cpu             I586_CPU
cpu             I686_CPU

Q: Do I comment out the "I386_CPU" and "I486_CPU"
lines to optimize for a Pentium, (& if not, how do I,) and
Q: Does it make a significant difference?

TIA.

Walter
