101 Jails:

last pid: 13467;  load averages: 21.09, 13.50, 19.54    up 17+12:23:50  13:43:55
1576 processes:4 running, 1572 sleeping
CPU states: 59.0% user,  0.0% nice,  9.0% system,  0.0% interrupt, 32.1% idle
Mem: 2553M Active, 649M Inact, 474M Wired, 157M Cache, 199M Buf, 9120K Free
Swap: 3072M Total, 184M Used, 2888M Free, 5% Inuse

I think I peaked that machine around 196 jails at one point, before we picked
up a second server as well as before we were able to do multiple domains
per VM cleaner then one jail each ...

the load average is mis-leading, as I've seen it hit as high as 1000 and still
allow me to type on the machine, in order to rectify the problem process(es) ...

God, I love FreeBSD :)
