I made a 64MB swap partition. I wonder if there are any particular options (systcl vm.* ?) that I should be intersted in to get the best out of the machine. I did sysctl -ae | sed 's/^/#/' >> /etc/sysctl.conf and went through all of it, but the descriptions (sysctl -ad) didn't really tell me much. The handbook advised me to put MAXUSERS 0 into kernconf, so that the systems puts a reasonable default value into kern.maxusers. Is there something more to tweak? Is there some documentation about running FreeBSD on a very lowmem machine? Some discussion of kern.maxusers? Thank you Jan
