By default, yes. However, you can force a particular number of cluster mbufs by setting NMBCLUSTERS in the kernel configuration (see the LINT configuration file) or by setting the kern.ipc.nmbclusters loader tunable (see /boot/defaults/loader.conf). See tuning(7) for more details. Bruce. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
