# add isolcpus to grub & disable irqbalance service

### ensure sda IO scheduler is CFQ if available
### don't set ionice if not, test with (assuming srcds is on sda)
# grep cfq /sys/block/sda/queue/scheduler
### expected output:
# noop anticipatory deadline [cfq]

# - put SRCDS server on CPU2
# - FIFO scheduling, high prio
# - IO scheduling to realtime, high prio (make sure CFQ is available before running this script
