Quote Jeremy Chadwich talking about vm.kmem_size:
"1) Consider increasing it from 512M to something like 1.5GB; do not
increase it past that on RELENG_7, as there isn't support for more than
2GB total. For example, on a 1GB memory machine, I often recommend
768M. On 2GB machines, 1536M. You will need to run -CURRENT if you
want more."
