CKVM Performance Tweaks

For the best performance, tweak your SSD-Cached KVM VPS with the following commands:

For an official ISO Install:
echo 0 > /sys/block/sda/queue/rq_affinity
echo noop > /sys/block/sda/queue/scheduler
echo "echo 0 > /sys/block/sda/queue/rq_affinity" >> /etc/rc.local
echo "echo noop > /sys/block/sda/queue/scheduler" >> /etc/rc.local

To potentially improve network performance:
echo "net.core.rmem_max=16777216" >> /etc/sysctl.conf
echo "net.core.wmem_max=16777216" >> /etc/sysctl.conf
echo "net.ipv4.tcp_rmem=4096 87380 16777216" >> /etc/sysctl.conf
echo "net.ipv4.tcp_wmem=4096 65536 16777216" >> /etc/sysctl.conf
sysctl -p

Extra Lines:
You can also add the noatime and nobarrier (barrier=0 for ext filesystems) options to your mounting setup (/etc/fstab). To remount without rebooting, use the -oremount option with the mount command.
