NetBSD claims a fair amount of memory for kernel data and disk buffers
at boot time.
The default kernel uses a bit more space than necessary since it has
all the device drivers and other things enabled. To get better
performance, you can build your own kernel by doing the following as
root:
mkdir -p /usr/obj/sys/arch/i386/compile/POLYS
ln -s /usr/src/sys/arch/i386/include /usr/obj/sys/arch/i386/include
cp /usr/src/sys/arch/i386/conf/ATHENA-AHA $HOME/POLYS
<Now edit $HOME/POLYS to remove things you don't want; lowering the
value of maxusers will also help>
config $HOME/POLYS
cd ../compile/POLYS
make depend
make
mv /netbsd /netbsd.old
cp netbsd /netbsd
At the moment, we can't guarantee that our kernel source tree will
always be stable (this will change in the fairly near future, although
it's not clear whether the 3C590 will be supported in our production
tree), but right now it should be fine (your current kernel was build
out of it).
