I see no other overhead than disk usage either on my systems, so I assume that must be
it. I set it up the pretty standard way described in jail(8). I have some custom patches
that allows things like top to run without kernel memory access too. Only limit for the
number of jails to run on a machine I've run into are disk and memory.
