Hello,

I was wondering what the MTRR option in the kernel configuration was.  It=
=20
surely feels like my system is actually faster without MTRR in kernel.

My kernel configuration looks as such:---------

# Sung's custom kernel configuration

---------------------------

This generates with march=3Dpenitumpro optimization in mk.conf, 1.3M for =
kernel=20
size.  I have been using this config forever and seems to work fine with =
my=20
purpose.  Is my configuration missing anything that need not be missing f=
or=20
proper workstation purpose other than networking (my laptop is not connec=
ted=20
to any network).  For example, I only have lool pseudo-device etc. =20

Lastly, I am using mfs for /tmp.  I need not have "pseudo-device md" for=20
simple mfs for /tmp, no?


Thank you.
