FreeBSD Jails with VLAN HOWTO

This article discusses how to set up jails on a FreeBSD 11-CURRENT system utilizing VIMAGE (aka VNET) to provide a virtualized independent network stack for each jail with support for VLAN tagging.

	# low latency is important so we highly recommend that you disable hyper
	# threading on Intel CPUs as it has an unpredictable affect on latency, cpu
	# cache misses and load.
	#
	# These settings are specifically tuned for a "low" latency FIOS (300/300) and
	# gigabit LAN connections. If you have 10gig or 40gig you will need to increase
	# the network buffers as proposed. "man tuning" for more information.
