HOWTO : Performance Tuning on Kali Linux 1.1.0

Kali Linux 1.1.0 is released recently. It is much faster than before. However, we can tune it for better performance too. Here we go!

Step 1 :

nano /etc/sysctl.conf

Append the following to the sysctl.conf :

sysctl -p

Step 2 :

nano /etc/rc.local

Insert the following before "exit 0" :

echo 1024 > /sys/block/sda/queue/read_ahead_kb
echo 1024 > /sys/block/sda/queue/nr_requests
echo deadline > /sys/block/sda/queue/scheduler

If your device is not sda, please change it accordingly.

Step 3 :

It is very danger for this step. Make sure you do NOT have any typing error; otherwise, you cannot boot your Kali up.

nano /etc/fstab

Locate "ext4" and add the following before "errors=remount-ro" :


If you are using LVM, it will look like :

/dev/mapper/kali-root / ext4 noatime,nodiratime,norelatime,errors=remount-ro 0 1

After that, run :

mount -a
mount -o remount /

If no error message, then reboot. If there is any error message, double check if you have any typing error or not.

That's all! See you.
