Subject: optimizing the kernel

hi I'm new (groan)

I am running FreeBSD 4 and I am unsure if my kernel is optimized for my
processor and ram. how do I go about this?

be gentle with me....

Find the CPU in the GENERIC kernel that is closest to=20
yours and comment out the others.  (Don't comment out=20
the line for the i386 architecture by mistake,=20
assuming that's what you have.)

Look in /etc/defaults/make.conf for a list of=20
processor types you can put in the CPUTYPE line.  Then=20
everything you build, including the kernel and FreeBSD=20
itself, will be optimized for that CPU type.  Don't=20
uncomment or change anything in=20
/etc/defaults/make.conf.  Instead,=20

cp /etc/defaults/make.conf /etc

and make any changes in /etc/make.conf.

Re optimizations for RAM - sorry, don't know of any.
