# ioscheduler configuration file

# Scheduler Descriptions. Taken from the kernel configuration documentation:

# The anticipatory I/O scheduler is the default disk scheduler. It is
# generally a good choice for most environments, but is quite large and
# complex when compared to the deadline I/O scheduler, it can also be
# slower in some cases especially some database loads.

# The deadline I/O scheduler is simple and compact, and is often as
# good as the anticipatory I/O scheduler, and in some database
# workloads, better. In the case of a single process performing I/O to
# a disk at any one time, its behaviour is almost identical to the
# anticipatory I/O scheduler and so is a good choice.

# The CFQ I/O scheduler tries to distribute bandwidth equally
# among all processes in the system. It should provide a fair
# working environment, suitable for desktop systems.

# Configure your schedulers below. Your choices are anticipatory, deadline, and cfq

# The default IO scheduler
def_io_sched=anticipatory

# IO scheduler on per-block-device basis. Uncomment and add/modify as needed.
# Note: RAM block devices (ram*) for not have schedulers.

# Floppy devices: 
#io_fd0=cfq
#io_fd1=cfq

# IDE devices 
#io_hda=cfq
#io_hdb=cfq
#io_hdc=cfq
#io_hdd=cfq

# SCSI devices (yes, there may be more scsi devices than those listed below)
#io_sda=cfq
#io_sdb=cfq
#io_sdc=cfq
#io_hdd=cfq
