### 10. 64-bit kernel
To increase performance, we're going to tell the Pi to use a 64-bit kernel. All the supporting software will still be 32 bit, but the code that manages memory and multitasking will be able to use the more powerful 64-bit mode.
As it stands, if you run `uname -a` you should see something like this:
```
Linux raspberrypi 5.4.51-v7l+ #1333 SMP Mon Aug 10 16:51:40 BST 2020 armv7l GNU/Linux
```
The key is `armv7l`. This tells you that you are on a 32-bit kernel. To change this, open up the config file:
```
sudo nano /boot/config.txt
```
And add the following two lines:
```
# enable 64-bit kernel
arm_64bit=1
```

Notice how `armv7l` has been replaced with `aarch64`. This tells you that you are now on a 64-bit kernel.
