On wcarchive, maxusers is 1000 and NMBCLUSTERS is 100000. Don't try that at home, folks, without kernel modifications. With the change to increase the kernel VM in 3.2, you should be able to crank both up significantly. 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
