jails

Just for curiosity. An example machine: an dedicated amd64 server with the last stable version of FreeBSD and UFS for the partitions.

How much resources consume FreeBSD for each empty jail? I mean, I don't want know what is the resource consumption of a jailed server or whatever, just the overhead of each jail.

I'm especially interested on CPU, memory and IO. For a few jails the overhead is negligible but imagine a server with 100 jails.
