# PROCESS SCHEDULING OPTIONS
# At the moment, ULE is in limbo. It gets the odd patch to it, but there's no
# active maintainer. Most of the benefits of ULE have been ported to 4BSD,
# but there's still room for improvement in both.
options		SCHED_4BSD
#options	SCHED_ULE
options		PREEMPTION		# Enables kernel thread preemption
options 	ADAPTIVE_GIANT	# Giant mutex is adaptive.
#
# These three options provide support for System V Interface
# Definition-style interprocess communication, in the form of shared
# memory, semaphores, and message queues, respectively.
# X11 depends on these.  Linux-compatibility depends on these.

#
# TCP_DROP_SYNFIN adds support for ignoring TCP packets with SYN+FIN. This

# for RFC1644 extensions and is not recommended for web servers.
#
options		TCP_DROP_SYNFIN		# drop TCP packets with SYN+FIN
#
# Zero copy sockets support.  This enables "zero copy" for sending and
# receiving data via a socket.  The send side works for any type of NIC,
# the receive side only works for NICs that support MTUs greater than the
# page size of your architecture and that support header splitting.  See
# zero_copy(9) for more details
