On wcarchive, maxusers is 1000 and NMBCLUSTERS is 100000. Don't try that at home, folks, without kernel modifications.

I can't say how much without doing a careful analysis of KVM usage. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
