This changes the default TCP Congestion Control (CC) to CUBIC. For small, transactional exchanges (e.g. web objects <15kB), this will not have a material effect. However, for long duration data transfers, CUBIC allocates a slightly higher fraction of the available bandwidth, when competing against NewReno CC.

# To describe a particular object, a block comment (if it exists) should

# comment on the same line if possible. Very detailed descriptions of

# A space followed by a tab separates 'options' from an option name. Two

# SCSI DEVICES
|
||
|
||
# SCSI DEVICE CONFIGURATION
|
||
|
||
# The SCSI subsystem consists of the `base' SCSI code, a number of
|
||
# high-level SCSI device `type' drivers, and the low-level host-adapter
|
||
# device drivers. The host adapters are listed in the ISA and PCI
|
||
# device configuration sections below.
|
||
#
|
||
# It is possible to wire down your SCSI devices so that a given bus,
|
||
# target, and LUN always come on line as the same device unit. In
|
||
# earlier versions the unit numbers were assigned in the order that
|
||
# the devices were probed on the SCSI bus. This means that if you
|
||
# removed a disk drive, you may have had to rewrite your /etc/fstab
|
||
# file, and also that you had to be careful when adding a new disk
|
||
# as it may have been probed earlier and moved your device configuration
|
||
# around.
|
||
|
||
# This old behavior is maintained as the default behavior. The unit
|
||
# assignment begins with the first non-wired down unit for a device
|
||
# type. For example, if you wire a disk as "da3" then the first
|
||
# non-wired disk will be assigned da4.
|
||
|
||
# The syntax for wiring down devices is:
